Greetings Newborn will loss  10% of it's weight during first 8days then there will be weight gain.If the baby is having urine output of 5-6times/day,enough sleep between 2feeds,and active then will call it as adequate feeding. Pet day around 8-12 feeds are adequate at frequency of 2-4th hrly. To increase breast milk mother should have adequate food and plenty of water, good bonding between baby and mother with correct feeding technique.For further queries kindly book online consultation with me so I can guide you.
