The experience of being a mother becomes truly immersive and three-dimensional because the baby with whom you share your blood is right in front of you, wrapped in your arms.
The 2-week old baby is still making efforts to adapt to this new environment. Compared with the mother's womb, the outside world is noisy and bright, which is somewhat unfamiliar to him.
However, you'll notice that the baby is making progress every day, and his adaptability is quite strong.
During the first week of life, most babies experience a temporary decrease in weight. This is due to their reduced milk intake, along with the expulsion of amniotic fluid, urine, and sweat, as well as respiratory losses that result in some body water being lost. A temporary decrease in weight occurs between 2 to 4 days after birth, which is referred to as "physiological weight loss" and generally does not exceed 300 grams.
As the breastfeeding volume increases, the baby's weight begins to rebound from the fourth and fifth days, and it can be restored to the weight at birth within this week.
You will find that your baby's limb movements are unintentional, conditioned reflexes. For example, when they hear a loud sound, their arms instinctively wrap around their chest, which is a unique reflex of newborns.
By the end of this month, you will find that as your baby's muscle control develops, his or her movements gradually turn into conscious behaviors.
From birth to 56 days, the baby also has a magical ability-walking reflex. Starting from the eighth day of birth, this innate ability can be used to train, which not only enables the baby to learn to walk in advance, but also promotes brain development. Maturity and intellectual development.
Some babies make a sound when they breathe, which is caused by the cotton fibers that fall off from their blankets and clothes, as well as more dust in the air. This can obstruct the baby's nasal passages and upper respiratory tract. However, there is no need to worry because the baby is not coming down with a cold. At this time, the baby is merely struggling to breathe.
You can try to use a cotton swab dipped in baby oil to clear the dirt out of the nose, but you have to be gentle and careful, holding the head of the baby carefully so that he doesn't move.
At three weeks old, the baby's conditioned reflexes have been established. When you separate his or her grasping hands and lightly touch the palm with one finger, he or she will firmly clasp your finger without releasing it. Similarly, when a mother holds the baby in her arms, preparing for breastfeeding, or when the baby cries due to hunger, it will wriggle its head from side to side, open its mouth wide, and push its chest outward in search of the mother's nipple. The baby has already mastered the essential techniques for sucking milk, making sucking movements with great force. If you gradually bring your hand close to the baby's face at a certain distance, it will instinctively blink its eyes.
Now the baby can look into your eyes, but the duration is not long enough.
When your baby gazes at you, it's important to look back at him or her with a loving smile and nod gently. Saying his or her name in a soft voice can also make them happy.
The baby can't yet consciously reach out to touch objects, but he/she enjoys the massage exercises you give him/her, as well as the gentle touches, kind voice, and friendly smile of mother.
At this time, the baby's body is still very soft, so you must pay attention to supporting the baby's neck and waist and buttocks when hugging him or her.
If your baby often cries and is upset for unknown reasons, and no matter how hard it is to coax it will work. In serious cases, it will produce paroxysmal crying, which lasts for several minutes before calming down, then your baby may have colic.
Generally speaking, there is about 20% of babies who start to have symptoms of colic at the age of 2-4 weeks after birth. During the attack, the baby will cry for a long time and look very uncomfortable.
If your baby exhibits this phenomenon, you will likely be quite troubled in the coming months, as this abdominal pain is functional and frequently recurs; there are no particularly effective treatments available. It will naturally improve as your baby grows older.
When an episode occurs, it is recommended that the baby be placed in a prone position and gently massaged on the back to help alleviate pain.
It is also permissible to administer sedatives for children according to the doctor's advice.
At this stage, babies have already begun to exhibit different personality traits. Some are prone to crying and activity, making it challenging to care for them; others are quiet and obedient, requiring little fussing and are particularly easy to manage. This is determined by the baby's different neurotype and temperament type. You can only adapt to your baby and may not easily change them.
This is going to test their patience.
Every baby is an individual, and it's important to respect their uniqueness so they can grow up happy and healthy.
The baby has now been full 3 weeks, and by this weekend, the baby will be one month old! The birth of the baby seems to still be just yesterday, but in the mother's view, this month is so long, enduring hardships, tasting all sorts of first-time motherhood. However, seeing the baby progress day by day, the mother's heart is sweet even though she works hard and feels tired.
Now baby's neck strength has been strengthened, he can lie on his back or the front of an adult, support the head with the belly and lift up the head a little bit. He can also turn his small head left and right.
If you lift your baby, or sit on your back, the baby's head can be held up for a moment, but not for long, because it is easy for the baby to get tired.
The coordination of the baby's arm and leg movements is improved, indicating that his or her ability to control muscles has strengthened.
Now the baby has initially formed his own sleeping, nursing and defecation rules and habits. Some babies can sleep for 4 to 6 hours at night, but the differences between babies are very big. Some babies still need their mother at night. Feed 2 or 3 times.
In particular, breastfed babies have short intervals between breastfed milk. Because breast milk is easier to digest, babies who eat breastfed also have more bowel movements than babies who eat milk and need more care from their mothers.
At this time, the baby can distinguish its mother's voice and smell. Even if the mother is not in front of it, as long as it hears its mother's voice, the baby will show excitement. If the baby is crying because of loneliness and boredom, it will also calm down quickly.
If you have given prenatal education to your baby, try playing music or stories that you often listened to during the fetus. The baby is likely to have a significant reaction.
Now the baby can determine the source of the sound. When hearing sounds coming from different directions, the baby's head will turn in this direction.
But the distance of the sound should not be too far, it should be within 50 centimeters.
The baby's eyes can now see people and objects at close range, and his eyes will follow the objects in front of him horizontally. He especially likes to see pictures with thick lines, simple patterns, and bright colors, especially the patterns of human faces.
Compared with the previous few weeks, the baby has made significant progress and looks more likable.
The average weight of a full-moon baby is 4.9 kg for boys and 4.6 kg for girls; the average length of a full-moon baby is 56.6 cm for boys and 55.6 cm for girls.
The unique characteristics of newborns at 5 weeks of age, such as being prone to startle and unstable movements of limbs, began to gradually disappear in the baby after a full month.
His limbs and hands are now much larger than when he was born, but during sleep they curl up like a baby frog.
Your baby has grown accustomed to the various sounds around them and is beginning to distinguish the source of these sounds.
He or she can stare at you attentively and smile at you when she is happy. The baby won't laugh at this time, but you can already see that he is smiling at you.
Now, when babies lie on their stomachs, they can lift their heads up. Some babies have even managed to raise their necks. However, it's important not to let them stay in this position for too long; every now and then, they need to lie down or rest against something flat.
Now, when you hold a toy in front of the baby's eyes and move it, the baby can keep looking at the object in front of them.
However, the most exciting moment for parents was when their baby started to "speak." At this time, babies would emit sounds such as "mmm," "aaa," "eee," and "yaya" to express their emotions and needs. It is important for mothers to respond promptly to these sounds. They can mimic the sounds of the baby and engage in "conversations" with them as much as possible. Even if you step away briefly and go to another room, you can continue to talk to the baby, ensuring that they hear your voice. This approach helps to calm their emotions significantly.
The lives of parents nowadays involve ceaseless care for a baby, changing diapers and feeding them, attending to their mouths and butts. They are so busy that they can't settle down or sleep well. This not only makes life hard but also seems somewhat dull. More seriously, some mothers may suffer from "postpartum depression," which requires the help of doctors and greater concern from family members.
Don't worry, this is not the entirety of your life in the future. It's just a phase of parenting. As your child grows day by day, you will see that your hard work has paid off with your child's healthy growth. This will make you even more cherish your own child.
