Daycare vs staying home


I have the option of keeping my 1.5 year old with me at home when my baby is born or having him go to day care full time where I can pick him up anytime throughout the day. I would like opinions on keeping him home with me and a newborn vs sending him to daycare in the morning when my husband goes to work. I’m looking more for input on development, by being around other kids his age will that be better than at home with me? Will keeping him home and having 1:1 attention besides my newborn be better than 5:1 kid to teacher ratio at daycare? Thoughts?
