What foods are you feeding your 4 month old?

Justia
Hi moms, 
For those of you starting with puréed/solid foods, what foods are you giving your baby? 
Rice cereal? Fruits? Veggies? 
How much are you feeding baby per day ? When do you feel comfortable switching to the next type of food? 
Please please comment below . FTM here and of course I'm a bit unsure of what to feed, when to feed what and how much at a time. My doc was very vague and my parents want me to feed baby all these things. I don't want to overfeed her . 
Thanks 😬
