I'm exbf my 2 month old DS but finding he's not really asking for it - I feed him if he's gone 3.5hrs without and he rarely asks for it before. He wakes in the night for feeds anywhere between 3 and 7 hours. He feeds well, growing steadily and has regular wet and dirty nappies. I think I'm paranoid if I just leave him to feed when he asks he won't get enough calories during the day and he'll wake more at night - should I just follow him?
