Feel like I'm doing everything wrong

C

I'm a first time mom and my son is 9 months. I feel like I'm doing everything wrong. He can't go to sleep without having his formula- needs it to fall asleep. I just realized that I should've changed the nipple size by now. Still had him on size 1 and he should prob be on size 3 by now. He is having trouble bearing weight on his legs bc he is very big for his age, but I can't help but think it's my fault like maybe I didn't leave him on the floor enough. Also in the middle of the night he always wakes up once during the night and won't go back to sleep till he's in my bed. I don't have to heart to let him cry it out. I don't know why I'm even posting this I guess just need to vent somewhere I feel ok to. I love my baby so much. But I really feel like I'm fucking up.
