A newborn’s nervous system is still maturing, but babies can accomplish a lot in their first month. You’ll notice that your baby was born with several innate reflexes, including sucking. Soon after birth, he will be able to (with a little help from you) latch on to a breast or nipple to feed. If you put your finger inside baby’s palm, you’ll notice that he’ll close his fist around it (and many a proud father has bragged about the strength of his newborn’s grip).
