My little boy has started demanding food every hour and a half. I'm pretty certain he eats plenty at each feed and at night he is able to sleep for 3-4 hours without waking to eat. I have been trying to space things out but he seems desperate after an hour and a half of not eating. He also often falls asleep at the breast so I think he maybe is using it to soothe himself even if he's not hungry. He is still very young so I don't want to leave him to cry but am I setting myself up for a fall letting this behaviour continue? Does anyone have any tips that might help?
