hi my baby is a week old today - i was wondering how long should i feed him on demand (breast) for before trying to get him into a bit more of a rountine. for eg he fed last night at 10.30pm, 12am, 1am 2am and then i tried to feed him at 6am but he wouldn't take any decent amount til 7.30am. was a bit worried he had gone too long by this stage?
