My LO is 11 weeks and for the past month he's been eating 5oz every 3 hours during the day and then 6oz first thing in the morning and an occasional 2-3 oz snack. He was eating between 28-30 oz every 24hrs. The past few days he's started only eating 4 oz at a time and going close to 4 hours between feedings. He's still sleeping through the night (9-5/6) and not grumpy so I don't think he's sick but it just seems weird to have him eat the same amount for so long and now to decrease. Has this happened to anyone else?
