A.M.
Give hubby a list of all the playgrounds withing 20 minutes of your house. Make it a challenge for him to see if he can get to them in less time than google suggests:)
The RI Mall is great for kids to just run and run in. (no one there!)They have the glass elevator to ride up and down in too.
Warwick Showcase does Kidtoons on the weekends. G rated films that are 3.50 to attend, under 3 years is FREE.
Check your local bookstores for storytimes. Those are always "free" and she is 14 mo. so you could get out of there keeping it that way!
All those gyms and music class type things usually offere a first class free. Nothing says you have to sign up. Nothing stopping you from taking all the free classes either!
Make grocery shopping a little father away:) (longer to go and come back, longer they are out)
"lunch" at Mc Donalds or some other place with a playplace. If hubby buys a drink and a small fry, they can stay till whenever undetected.
Hope that helps!
