Are there daycares that offer just like 2-3 days a week?

Or days that can change weekly?

Im going back to work full time starting August 1st.. (baby will be 4 months old) and granted between my in-laws, my aunt, parents, and one friend I don’t have to do daycare.... but i do wonder if it is better for him to go to all those different places every week or maybe just my in-laws and day care a couple days...

I can guarantee he will get the proper tummy time, nap time, socialization etc etc things that day care has routines for... The people i have watching him - i trust 100% but i feel like they don’t care about that stuff as much as i do... is that dumb? Thoughts?
