My son is nearly 4 months old & up until 2 weeks ago slept 12 hours at night without feeding then one weekend he changed. He usually has 6oz of milk 3 times a day & then 7oz before bedtime. Now he will not eat more than 4oz at a time but will not eat more regularly either. I have tried dream feeding him 2oz at night as i'm worried hes not getting enough to eat he's also started waking up at 5am. The only difference is he's just learnt to roll over, any ideas????
