12mos check up

How did go for you parents? We went to ours and the doctor mentioned bf babies tend to be more picky eaters and was kinda hinting to wean off. He explained that there’s not much nutrition baby will receive from breast milk from here on out and will miss out on nutrients from food. But I explained that baby eats table foods and bf only for comfort. Yes she has days when she eats a lot more then others. Any other moms heard of this? Or what’s ur experience breast feeding baby past 12 mos and eating table foods? Weight gain? Thanks in advance
