Feeding & sleep schedule (6mo old)

Ariel

I've been trying to get my smallest girl on a good eating and sleeping schedule. She's very clingy and has been since day 1. I need any and all tips on how I can begin to get her to start sleeping on her own in her pack n play. When to feed her fruits and veggies (day/night), how much to feed her and how much of a bottle I should give her afterwards. It just feels like we BLOW through formula!
