We did Kids bowl free last summer. She got shoe rental and two free games daily. We also did regal's summer movie series. Unfortunately that doesn't help with the winter time.
We have just started doing the Girl scout parents night out. For $10 she gets to do crafts, watch movies and play games. Many community center's have these for school age kids.
Still young enough for bounce houses and jungle gyms
We get invited to a lot of birthdays
Most of our museum's have a free night
Nature center (who cares that its winter)
We have a children's membership at the YMCA yes mine let you get a solo membership for just the child so swimming is includes, We do gymnastics every Tuesday night really want to keep her in after school sports or activities.
I am always on the go with the kids I say get your kids involved with groups. Often you get a group rate. I haven't paid for the zoo in a while. We tag along with a friend who has a membership.
Subscribe to local blogs. They have a ton of ideas. I have pages on my Facebook for thing we like to do. Friend your local bowling ally and you will know when they are running specials
