We started our LO on EASY about a week ago he was doing ok in the day time eating 5-6 oz every 3-3.5 hours. the last two days he has been very cranky and not eating as much. He only eats about 3oz and has stretched his feeding to 4 hours since he wasnt taking the bottle at 3 or 3.5 hours. his naps have also started to become very sporadic. He used to nap 1.5-2 hours w/o waking up. Has anyone had this same experience before? please help
