The groups meet weekly according to the child's age. For example, the group I would go to would be the 0-2 year olds which meet on Tuesday at a group member's home. They also have monthly meeting in the park which is what I went to today. There were about 12 moms and 20 or so kids. They had a craft table, snacks, and a raffle. There are also various other activities the Club members can partake in such as going to museums, movies, and dinner. They even have a service day where they give something back to the community.
I highly recommend any mother out there to get involved in their local MOMS Club if they have the opportunity. We moms need all the support we can get!
