Feeding Schedule for (almost 6 month old)

Hey mamas... I’m just trying to figure out feeding schedule for my almost 6 month old.

We just upped his bottles to 6 ounces every 4 hours. He has been eating solids since Thanksgiving — fruits & veggies.

I just introduced oatmeal (our doc said skip it and go straight to solids).

My question is how many times a day to you feed your baby solids and how many ounces of formula / breastmilk per feed?

He is waking in the middle of the night and I’m not sure why, we’re trying to get I’m on a good eating and sleeping schedule since we both work 🤦🏻‍♀️ the struggle is real!
