1, a small baby will make a “giggling, giggling” sound when defecating, the whole body will turn red do not worry. This is because the fetus in the womb no bowel movement, his abdominal muscles lack exercise, so there is not enough strength. After birth, the baby has to push very hard to expel the stool. 2. Most of the red rashes on the little buttocks are caused by the baby’s stools. The newborn’s digestive system has difficulty digesting the carbohydrates in breast milk or formula, and the undigested ones ferment in the large intestine, producing gas, acid, and foamy stools – which can be very irritating to the baby’s tender little buttocks. Be sure to change your baby’s diaper regularly and rub more buttocks cream. 3, baby’s toenails look like they are growing into the flesh which is normal. The nails of small babies are easily folded and bent, and are deeply placed in the nail bed. To determine if there is a problem with your baby’s nails, just gently squeeze his toes: if your baby’s toenails are really growing into the flesh, your baby’s feet will feel pain and he will tell you by crying. 4, the baby has a pair of “flat feet”. In fact, it is normal for newborns to have flat feet. On the contrary, if the baby has high arches in the first few months, it is a bad sign, because it indicates that the baby will have neurological or muscular problems. The arch will not be well developed until the baby is 4-6 years old. 5. Clubfoot and rotundity. Due to the limited space in the womb, the fetus grows in a position where his legs are crossed and curled and his hips and knees are stretched, so his legs and feet are bent inward. After birth, with the baby’s regular exercise, the muscle strength of the hips and legs will strengthen, and the baby’s body and feet will slowly become straight. 6, sometimes the baby looks a little “right-eyed”. The muscles of one eye are stronger than the other, which can make the baby sometimes look a little “right-eyed”. This phenomenon is only intermittent, do not worry. 7, the newborn baby can only breathe through the nose. This is because the newborn’s throat position is relatively high. The higher throat position allows him to breathe while eating milk and ensures that liquid does not flow into the trachea. The disadvantage is that the baby cannot breathe through the mouth. If your baby has nasal congestion, you should use a nasal aspirator to suck through the nose in time. 8, newborn babies do not shed tears. This is because the amount of fluid produced by the newborn’s tear ducts is very small and can only keep his eyes moist. Moreover, when the baby is born, its tear ducts are partially or completely closed, and can only be fully opened after a few months. 9, the baby’s breathing is fast and irregular. The breathing rate of newborns is relatively much faster than that of adults, and it is also irregular. This is because the baby’s lungs are still small and its nervous system is not fully developed. 10. The baby’s body temperature is irregular. The newborn baby’s thyroid gland – the baby’s internal thermoregulator is not yet well developed, and the sweat glands are not developed enough, so the baby’s body temperature will be high and low. The good thing is that the baby has enough fat to protect, the body temperature will not drop too low. 11, newborn babies are prone to dehydration. Although seventy-five to eighty percent of a newborn’s weight is water, but because the metabolism of newborns is fast, two to three times faster than that of children or adults, resulting in rapid water loss, so small babies are prone to dehydration. To determine if your baby is in a dehydrated state, put your pinky into your baby’s mouth, if it’s moist it’s fine, if it’s dry and sticky, it means your baby needs milk. 12. Newborn babies love hiccups. Babies have been having more frequent hiccups for a few months after birth. This is exercising the diaphragm, which plays a vital role in the baby’s breathing movements. Sometimes the hiccups are due to your baby being overly excited, other times they are due to having just breastfed, and to some extent they are due to the diaphragm not being developed yet. By the time you reach three to four months, your baby will have fewer hiccups. 13. Newborn babies are easily hungry. A newborn’s stomach is only one-fiftieth of an adult’s. Because of the small capacity of the stomach, so the baby will feel hungry again in a short time. 14. Soft little ears. The newborn baby’s little ears are so soft that they look a little like beckoning ears. In fact, this is only because the cartilage in the baby’s little ears has not yet developed well. After a few weeks, as the cartilage matures, your baby’s little ears will slowly harden, stand up and have a normal shape.
