Each year I always start to panic when the rain starts and my kids are jumping off furniture to burn off energy. So, this year I decided to write a list of fun ideas to do with kids during the lovely NW winter months. Here ya go...
Library - craft times, special events, story time, check out books and movies
Tacoma Children's Museum
Olympia Children's Museum - AMAZING!
Lattin Cider Mill (love this one - donuts, animals and lots more, Olympia area)
Point Defiance - hike through the woods in the rain or head to the zoo/aquarium
The Outlet Collection (formally known asAuburn Supermall) Head to the play area, grab coffee and let your kids run wild. They also have an indoor carousel!
Fort Steilacoom - play on the awesome castle play area, walk around the lake, explore! (cloudy day fun)
Chambers Bay Playground - another cloudy day - don't go if it's raining or windy.
253skate - rollerskating fun!
Ride the Link to Learning Sprout - park at Freighthouse Square and ride to the end, walk to Learning Sprout
IKEA - it's a bit of a drive but you can check your potty trained kiddos into the play area for one hour, in case you need a break :)
Discovery Village - I haven't been here yet, but, I've heard great things. Look on Groupon or Living Social for deals.
Pump It Up - look for coupons online
Odyssey 1 - kids can crawl through tubes for hours!
Tacoma Mall - grab some quarters and have your kids ride the cars/trucks/boats near Sears and then grab coffee and let the kids run around in the play area (it's a very sad and small play area but it works great for toddlers)

I hope this helps with your sanity during the NW winter months. Please feel free to add any other ideas you have or know of in the area!
