Ive also posted this in weaning for traffic:
My 8 month old baby used to be a fantasic sleeper, napping in the day then going from about 9pm til 6ish in the morning. However since hes started on solids he seems to be waking up at night and wont settle til he has a bottle. I still try to give him formula in the day but he will either only have a little bit or will just mess around with the the bottle being too nosy at his surroundings. He still has a bottle before bed and finishes it though. My daughter went the same way and at 4 years old still wakes in the night im hoping he wont be the same
