what would you do?

I've got a little dilemma on my hands.

My boyfriend wants me to get a full time job. which is fine. thats not the issue. the issue is that even if we were to both be working full time we can't afford to put our daughter (almost 9 months old) in day care. His mother can't work due to disability reasons so he's going on about his mom will watch her while I work and (he works 3rd) he will pick her up after he's done sleeping. and I just really really really don't want her to do this. I don't like how she does things. she has zero respect for my wishes. she does everything super old school even though most of those things aren't deemed safe. she and her husband (not my boyfriends biological father) are always trying to feed her candy and ice cream and junk food that she doesn't need. They don't feed her plain bottles. they always put cereal in them. they always tell me I need to give her Orajel for her teeth (which is NOT safe anymore) and she's not even fussy about her teeth. I co sleep with my daughter and she WILL NOT nap over at their house. We just have such a good routine right now I dont want to mess it up. I need advice mommas 😔😔😔 posting this here in hopes of more feed back
