Does it seem like all your baby does is eat and sleep? If so, pat yourself on the back, mom and dad—that is exactly what your newborn should be doing right now. The fact is your baby is growing right before your eyes.
It is normal for babies to lose weight within the first three to five days after being born. If fed properly, they should be back to their birth weight by 2 weeks of age. If you find that your baby seems regularly unhappy, in pain or spitting up an entire feeding, contact your pediatrician.
