I think she is not getting full off of my milk. I nurse her. Can I give her baby food yet? She will not under any circumstances take the bottel

She should not be given any sort of solid food until she's at least 4 months of age. In other words, no, you can't give her baby food yet. Even when she's 4 months of age you wouldn't start with baby food, only pablum, and only a spoonful or two a day for the first few weeks. She would still be mainly nursed or bottle fed.

Why do you think her fussiness is due to lack of nutrition? Is she gaining weight? Is her pediatrician concerned about her weight gain?
