At the time of birth, your baby weight included excess body fluid, which baby lost during her first few days.
Please don’t worry if your baby lose about one-tenth of birth weight during the first five days, then regain it over the next five, means about day ten your baby usually are back to her original birth weight. Some babies grow very quickly after regaining their birth weight, almost during growth spurts, which occur around seven to ten days and again between three and six weeks. The average newborn gains weight at a rate of 20–30 grams per day and by one month weighs about ten pounds 4.5 kg. Baby grows between 1 1⁄2 and 2 inches (4.5 to 5 cm) during 1st month. Generally we observed that Baby boys tend to weigh slightly more than baby girls (by less than 1 pound, or approximately 350 grams). Baby Boys also tend to be slightly longer than the baby girls at this age (by about 1⁄2 inch, or 1.25 cm).
Your paediatrician will pay particular attention to your child’s head growth, because it reflects the growth of baby brain. The bones in baby’s skull are growing together, and the skull is growing faster during the first four months than at any other time in her life. The average newborn’s head circumference measures about 13 3⁄4 inches (35 cm), and it grows to about 15 inches (38 cm) by one month. Because boys tend to be slightly larger than girls, their heads are larger, though the average difference is less than 1⁄2 inch (1 cm).

During these first weeks your baby’s body gradually will straighten from the tightly curled position when she was inside the uterus during the final months of pregnancy. Baby will begin to stretch his/her arms and legs and may arch her back from time to time. Baby legs and feet may continue to rotate inward, giving him a bowlegged look. Don’t panic this condition usually will correct itself gradually over the first year of life. If the bowlegged appearance is particularly severe or associated with pronounced curving of the front part of the foot, your pediatrician may suggest a splint or a cast to correct it.
Skull Shape – If your baby was born vaginally and her skull appeared misshapen at birth, don’t worry it soon should resume its normal shape.
Swelling – If you find any bruising of the scalp or swelling of the eyelids that occurred during birth will be gone by the end of the first week or two.
Eyes – If there is any red spots in the eyes will disappear in about three weeks.
Hair – You may discover that the fine hair that covered your child’s head when he/she was born soon begins falling out. If baby rubs the back of her head on her sleep surface, baby may develop a temporary bald spot there, even if the rest of her hair remains. Loss of birth hairs is not medically significant. The bare spots will be covered with new hair in a few months.
Another normal development is baby bad skin — pimples that break out on baby face, usually during the fourth or fifth week of life, they are due to stimulation of oil glands in the skin by hormones passed across the placenta during pregnancy. This condition may be made worse if the baby lies in sheets laundered in harsh detergents or soiled by milk that she’s spit up. If your baby does have baby spots, place a soft, clean soft towel under baby head while she’s awake and wash her face gently once a day with a mild baby soap to remove milk or detergent residue.

Skin – Your newborn’s skin also may look discolored, ranging in color from pink to blue. Baby hands and feet in particular may be colder and bluer than the rest of body. The blood vessels leading to these areas are more sensitive to temperature changes and tend to shrink in response to cold. As a result, less blood gets to exposed skin, causing it to look pale / bluish. If you move her arms and legs, however, you should notice that they quickly turn pink again.
Body Temperature: Your baby’s internal “thermostat,” which causes baby to sweat when it hot or shiver when its cold, won’t be working properly for some time. Also, in these early weeks, Baby will lack the insulating layer of fat that will protect her from sudden temperature shifts later on. For these reasons, it’s important for you to dress your baby properly—warmly in cool weather and lightly when it’s hot. A general rule of thumb is to dress her in one more layer of clothing than you would wear in the same weather conditions. And avoid baby from extreme conditions i.e. don’t take it too hot or too cold.
Umbilical Cord – Between ten days and three weeks after birth, the stump from the umbilical cord should have dried and fallen off, leaving behind a clean, well-healed area. And rarely a raw spot is left after the stump is gone. It may even discharge a little blood-tinged fluid. Just keep it dry and clean (using a cotton ball dipped in rubbing alcohol) and it will heal by itself. If it is not completely healed and dry in two weeks, in that case immediately consult your pediatrician.
