What is everyone feeding their baby when you start them on solids?

Tamara • Mommy to my 2 beautiful baby boys, Nathan Louis💙 born August 12, 2017 and Parker Joseph May 6, 2019❤️ My whole world😍

I’m going to in a month, and my pediatrician said 1 vegetable and oatmeal once a week. Just curious how everyone else is doing it ?
