Help...DS has got into a pattern where he doesn't want to feed during the day, instead preferring to have a massive feed at 3am. I am still exclusively breastfeeding but he has been on solids for a month and is having three reasonably hearty solid meals per day. I offer him the boob at 7am, 11am, 3pm and 6pm, but increasingly his is not interested and drinks just a little, if anything. Then he glugs for half an hour at 3am every night. He is maintaining a healthy weight (75th percentile) and seems happy enough. I know it's not so bad as it's just once a night, but I am pretty exhausted after 7 months of sleepless nights. Also, I am going back to work soon and not sure how I will cope with early starts plus night wakings. Any tips?
