We go to baby groups a few times a week. We have a children's centre which is free and most of the sessions you just turn up. We are starting another group which we've booked for in September and we go to a play centre too
Not a SAHM but I work partime and my baby doesn't go to daycare, he goes to my mums. We do 2 classes a week and he interacts with other babies. Occasionally we will do play dates/go to play areas as well but again more interacting with other kids more than actually playing with them. Also sees older cousins 1-2 times a week.
Have you looked for local council run childrenās centres? Iāve found several groups that way. Also some local run stay and plays, I found some great ones via Facebook. And any local community centres or libraries usually have sessions you can drop into and donāt need to book.
