Unsure which child care to go with

😞 I have to return to work soon when my baby turns 12 weeks. I enrolled him in a daycare down the street however, a friend of mines mother said she could watch our baby. The daycare would be $500 more expensive each month, and saving would benefit us a lot as we are not very financially well off. But part of me is concerned with my friends mom as I know daycare is probably more equipped for infant care (crib, safe sleep, playing with infants, updates). My friends mom already cares for 4 kids. I’m unsure of the ages but I am meeting with her this weekend to ask questions. What would y’all do? I could get a play pen for him while stays with the mom in regards to sleep? Would he be less susceptible to getting sick with less kids around? Any suggestions regarding that route? Thanks.
