Also, all new babies still have Mom's hormones circulating in their bodies. In boys, these hormones enlarge the testicles; in girls, they cause the labia to swell.
Genital swelling subsides over the first couple of days. In the first weeks, it might feel as if you're feeding your infant around the clock. Her frequent demands are nature's way of increasing your milk supply to meet her growing appetite. Breast-fed babies also tend to eat more frequently, because breast milk is more quickly digested and more completely absorbed than formula.
The reason for the feeding frenzy, of course, is that your little one has a lot of growing to do. She'll double her birth weight in six months, which requires a huge caloric intake.
Expect your baby to be particularly ravenous during growth spurts; the first typically occurs between 4 and 6 weeks of age.
Just be careful that you don't misinterpret her cues as hunger when all she may want is comfort or closeness, says ob-gyn Glade Curtis, M. If she has eaten within the last two or three hours, try holding and swaddling her to see if that calms her down. Before you crank up the thermostat or wrap your little one in another blanket, feel his torso. If it's warm and pink, your baby isn't chilled. Because his circulatory system is still developing, blood is shunted more often to vital organs and systems, where it's needed most.
His hands and feet are the last body parts to get a good blood supply. It can take up to three months for his circulation to adapt completely to life outside the womb. In the meantime, it's common for his tiny fingers and toes to feel chilly and look pale. As your baby becomes more mobile and active, his circulation will improve. The same maternal hormones that cause swollen testicles and labia are also responsible for the bloody vaginal discharge that newborn girls sometimes have.
Don't worry if you see a small smudge of blood or a bit of staining on your baby's diaper in the first weeks of life. This mini menstrual period usually lasts only a few days, Dr. Curtis says. Sometimes, what looks like blood may actually be concentrated urine, which can look quite dark in the folds of a diaper. Bright red blood, however, is unusual and warrants medical attention.
Many newborns develop a nursing tubercle or blister from vigorous sucking on a bottle or breast. In some cases, the blister is present at birth because of thumb-sucking in the womb.
Within the first two years of life, your baby's brain and central nervous system undergo a lot of developmental change and maturation, Dr. And for the first two months, baby's life is especially affected by these changes.
Trembling and quivering should come to a complete stop after this period. Overactive reflexes can result in chin and lower lip quivering as well as jittery limbs multiple times a day. Another factor that can cause newborn tremors is high levels of hormones like norepinephrine, which functions similarly to adrenaline. The hormones have a stimulating effect which can manifest in tremors and uninhibited movements.
Over time, these hormone levels decrease, which also puts an end to baby jitters. Jitters and jerkiness can be caused by the same neurological changes, but Lewis says jerky movements are "slightly more worrisome than tremors or jitteriness.
