Your 3-week-old

How your baby’s growing:

Babies love and need to suck, so don’t discourage it. In fact, you may have already discovered that a pacifier works wonders in helping your baby calm down. When the “binky” or your finger isn’t available, your baby may even be able to find her thumb or fingers to soothe herself.
