You are right down the road from me! I live in Hebron. My son is 18 months, and we don't get out too much either. There is a new toy store in Colchester where Eblen's used to be called Hide and Seek. They have a HUGE play area and they charge 5 dollars an hour for your kids to run around and socialize. It's mostly young kids as far as i know (1-3). My son and i also go to the mall and walk around. Buckland Hills has a Carousel that is i think 1 dollar per ride? Also the pet store is a big hit with my son. We can spend over an hour there just looking and learning about all the animals... and it's free. Lets see what else... The Great Escape in Glastonbury is pretty cheap for children under 3, and it is also huge! I went with my son a couple months ago, but he was a little over stimulated. I think he was a bit young for it. Your daughter is older and would probably love it! McDonald's Play Place is always fun and cheap. Another place my son loves believe it or not is the Bob's Furniture store in Manchester. He loves the Coy pond, free candy and mini golf course.
I feel for ya. I'm a stay at home mom and am pretty broke too... Lets pray Spring comes soon!
