My son is 13 months and just started playgroup for the first time. He is the youngest in the class (the playgroup is for 13 months to 23 months only). So far he likes to play with toys and have some interaction with other kids.
The playgroup my son is attending is about 10 mins away. I put him in the stroller and walk. The stroller can be parked at the playgroup reception area. Find a playgroup that is near your place is the most ideal.
