My 4 month old boy is only eating 4oz of formula at every feeding. About every 4 hours. He used to sleep through the night from 10:30pm to 7:00am, and now gets up at 3:30am and 5:30am for feedings. He eats 2tbsp cereal and fruit in the morning. Tbsp Veg and Tbsp fruit for lunch and 4tbsp cereal in evening. Should he be taking more formula per feeding, if so how do I get him to take more at each feeding? He also has no problems falling asleep, goes down awake and goes right to sleep. Sometimes he just snacks as well. Let me know, I am a confused 1st time mom.
