My baby is 5 days old and she needs to drink a 60ml bottle but she does not finish the bottle jow do i get het to drink?

May not be necessary: A 5 day old needs 600ml of formula in a day. They may not take the full amount but as long as their skin and eyes don't look yellow, they are making 1 poop a day and 6-8 wet diapers a day that may be ok. Infants are great at letting you know when they are hungry. They bring their hands to their mouth and suck on them (and of course they cry). Check in with your pediatrician at the 1 week visit.
