Meals for infants

NM

So the doctor told me she should be eating 3 meals a day but I’m just wondering could 1 meal be purée and a bottle or it has to be full blown meals? I just thought about this which is why I didn’t ask the pediatrician. Also any suggestions for meals for lunch? Or how did you start off feeding 3 meals a day? I just need help in general because I’m a picky eater & I don’t want her to be. She’s 9 months btw.
