I’m stuck on what to do!

I’m currently breast feeding my one week old and I kinda want to switch over to formula, only because I want to get back to my old routine (waking up with my one year old, cooking breakfast, putting him down for naps and bedtime actually me getting sleep) right now it’s not possible because she has to eat every 2-3 hours. If I formula fed her dad could feed her while I do those things, I just feel guilty not breast feeding her. I’m stuck 😫
