When my son was an infant, we joined the mother's group at Beverly Hospital. It is free to go for your first session and $5 a week thereafter. It's a great way to meet local moms in the area (many were from Marblehead, Swampscott, Lynn, etc.) and had babies the same age. I think the group for babies 4 months-12 months is on Thursdays at 10 am at the Hospital. You could certainly call the Hospital for more info. (They welcome everyone -- you don't have to be tied to the hospital in any way, which is nice.) Also, there is a guy who plays music in South Hamilton (a little drive from Swampscott, I know)for free (although he does like to receive tips since there is no charge and he does it for free). He plays on Friday mornings at 10 am the Hamilton Wenham Community house on RT. 1A. It's fun for the kids (tons of babies are there) and a nice way to get out of the house and meet people. My son is 18 months old and I totally know what you are going through. The mother's group definitely helped me get out and meet some new friends!
