DD (23 m) has refused all solids for 6 days now and only asks for milk. She's losing so much weight as a week ago was eating like a trooper. I think she may have had hand foot and mouth as its rife here and she had an ulcer on her tongue and spots on her bottom, but this has been going on for nearly a week. How long can toddlers survive on milk alone? I've tried everything to tempt her back to food - lollies, ice cream, all of her favourite meals (even fairy cakes) but an absolute flat refusal.I'm giving her floradix in the morning and paracetamol if her temp rises or she shows any discomfort but I don't think she's had the virus badly as there's been no sign of blisters, so surely she should be getting better by now? I went to the doctor who told me to "stick with it" but didn't give her much of a check up and I'm tempted to take her to the children's hospital as my instinct says something else is happening. She's been finding it really hard to sleep over the past 3 nights and is terribly lethargic. This is not my little girl, her sparkle has gone. Should I be doing anything else? If it was teething, she'd at least try and eat something, so I don't think its her 2nd set of molars.
