Am I expecting too much of DD (19mo)? She had a sickness bug last weekend. She's barely eaten since, although has had breastfeeds and demanded cups of cows' milk. She's had a bit of breakfast cereal today and and a yoghurt. Seems to want food but then screams at the sight of it. Is this usual? I'm guessing it is. Had wanted to keep her off dairy for a few days on advice of gp last time she had d&v, but she has really only wanted milk and yoghurt.
