Hi Anita,
Hope I can offer some words of reassurance.My DD,now 18 months went off milk at Christmas,she was also having a bottle before breakfast and before bed.She gradually started having less and less,until she point blank refused to touch it.I think she was possibly teething at the time,and she had a very bad cold over xmas when she hardly ate or drank anything so everything coincided at once.I gave it a couple of weeks then spoke to a health visitor who said not to worry,and that aslong as she was getting plenty of calcium in other forms eg milk on her cereal,yoghurt,cheese etc then she should be ok.I really worried at first and I still try to get her to have some milk in a sippy cup or straw cup.She'll have a few sips,then leave it.I've just come to the conclusion that she's gone off milk,as some children do.I can see thats she's putting on weight and she has a healthy appetite otherwize,so i'm not going to agonize over it.I hope this reassures you a bit.Keep offering it to her,but there is calcium in alot of foods,and milk can be used in lots of forms.Have you tried offering her milkshakes or smoothies now and again,made with natural yoghurt.It is difficult not to fret over it,but i'm sure she'll be fine.
Good luck
Clare
