toddler eating

My daughter is 1 years old and all she wants to do is drink milk . She wants to drink milk (cows milk) more than she eats food . Sometimes I have to force her to eat because all she wants to do is drink milk . Not water or juice . Just milk . Sometimes she'll drink water . She's not under weight but I'm afraid she'll start loosing if she doesn't start eating more . I think she thinks milk is still food . Anyone else experiencing this or has ?
