Having been a good sleeper since about 4 months DS has now suddenly (at 10 months) decided he has to have a bottle at night too. He's getting about 600ml milk during the day, plus 3 solid meals and is very active. He doesn't seem to want more food during the day but wolfs down the milk at night (and there's no set time for this - can be 10pm or 4am doesn't seem to make a difference).
Am at a bit of a loss? Any suggestions?
