So at a month old she is supposed to be eating up to 3 oz every 2 to 3 hours (on demand) from my understanding. However my little one is not satisfied unless she is getting closer to 4 oz. Her timing is off because she sleeps sometimes for 3 hours and then sometimes 1.5 hours. But when she wakes up, she wants to eat. Is this to much? And does going up to 3 hours in the middle of the day between feedings cancel out her eating every hour and a half in the evening?
