We just moved to Stamford in June. I have a 7 month old little boy and a 2 1/2 year old boy. I joined this meetup.com mom's group:
It's very active although most of the kids may be more toddler age. They do monthly mom's nights out too.
Feel free to e-mail me at [email protected] if you need any info. I'd be happy to meet up sometime as well. It'd be nice to start meeting some moms with children closer to DS #2's age!!!
