I don’t know what food you give her. If you put salt in it either reduce the amount or not put any in, If you use herbs & spices, onions, garlic, leeks etc. she may not like the flavours. Some foods are acidic and little ones either dislike the flavours or work out they give her indigestion. Citrus and tomatoes are definitely acidic and can cause a range of medical problems. Start with soft food and gradually give her more she has to chew. It’s a bit hard to make constructive suggestions. Is she at the age she is drinking more milk than she should be???

You haven’t mentioned the age?? If she is otherwise healthy and gaining weight and growing as she should, there’s not much to worry about. Just keep offering different foods regularly and she’ll soon get the hang of eating
