How do I know if Im overfeeding my baby?

Br

Honestly she loves solids. I make sure to breastfeed her an hour before her meals. She eats till she pukes unless I cut her off. How do I estimate what to give her?

She is gaining weight pretty slow. But I think she was weighed wrong at her 6 month appointment.

Im just want to make sure she isnt too full of the wrong things.
