My dd is 7 months old and up until now she has been great having her bottle in the mornings. But now she does not drink, she has a bowl of porridge and then I normally give her milk but she now refuses it. She has no teeth... could this be the problem that her gums are sore? She has two other bottles one at tea time and one at bed time and she has yogurt in teh day, should I be worrying about her not getting enough milk?
