Daycare question

I’ve been extremely blessed to be able to work from home since baby came and have been able to stay with her the whole time, but now that she’s 6 months and eventually I’ll be going back to the office, we want to start daycare hopefully this month, if not early February. Originally I wanted to do part time, like take her a couple days a week, but I’ve read that it’s not good and babies have a harder time going part time rather than starting full time; anyone have any input?? Any advice on how to prepare her and ME??
