My playgroup thing did not pan out very well, so I have cancelled it. Not enough attendance
However I have started to go to a place called "Off the Wall Gymnastics" on Tuesday or Thursday evenings throughout the summer from 5:30-7pm. They are located on Rt. 125 in Plaistow, about 7 miles south on rt. 125 from the Carriage Towne Plaza in Kingston (the one with the Dunkin Donuts). It is nice because the place is all padded and my daughter can run around and play without fear of her falling down and hurting herself.
There is also a La Leche League meeting in Stratham the 1st Wednesday of every month from 6:30pm-8pm. It is at the Coastal Family Birth retreat in Stratham, located on Frying Pan Lane. From Fremont it would take you less than 1/2hr to get there. (3 min from Exeter Hospital if you know where that is) There next meeting is August 5th. This might be a good way to meet other moms. They also have a day meeting, but I don't know when it is, because I work during the day.
There is also a place called "Sprout About" in Stratham that is open from like 9am-3pm. It is a big indoor play area for young kids. Again I haven't been because they are not open when I get home
Hope these things help you, if I think of anything else I will let you know.
