My baby is only 10 days old and he weighed 7lbs and 0.9oz at birth. on Thursday my healthy start nurse weighed him and he weighed 7lbs and 0.4oz. I've been feeding him every 2-3 hours and once I go to sleep I set an alarm to go off around 2-3 hours just to wake him up to change and feed him. Should I let him sleep until he wakes up for a feeding and how long should I let him sleep throughout the day before feeding him??please help!!
