My six month old has been weaning for about three weeks, coinciding with going into her own room. She's taken to sleeping alone pretty well, waking usually no more than two or three times a night. She has formula at night (BF during the day) but her appetite is HUGE. For a night feed 210 ml is normal and sometimes not enough - she'll sometimes need a top-up within half an hour, and is soon wet through. She can easily demolish three of these big bottles a night. I know there's a lot going on at this age - sleep training, weaning, developmental leap - but is this three bottle a night appetite normal? It seems so extreme.
