what to do with toddlers in Seattle?

Aquarium is a good choice.

I can't say I've ever looked through the kids clothes at the thrift stores here, so i don't know who's got the goods. But as far as places to go in general, there's a Goodwill and a Value Village in Ballard. Downtown has a Goodwill and a Goodwill outlet. There's a Value Village in Capitol Hill and a smaller thrift store (can't remember the name) right across the street from it, but I don't think the small store has much in the way of stuff for the kiddies. I don't know of any else beyond that! I'm sure there are more, and I'd like to know where they are too.

Donut or whoever else, does Fremont have any actual thrift stores rather than the expensive used vintage stores?

As for thrift stores, my route goes like this: Take the 5 north to Lynnwood and then work my way back to town, along aurora: two value villages, the DI, a goodwill, a st. vince's. I've found a ton of good stuff along that route.

I second jergins on the Aurora/99 corridor for thrifting. There are a couple big Goodwill/Salvation Army stores down our way (south Seattle), but 99 seems to have more thrift/mile.

at U Dub, I'd add the childrens section of the bookstore and maybe the Burke museum

There's a fabulous toy store in Pioneer Square called Magic Mouse.

(geez.)

Things are pretty bad right now, power off for lots of people, bad flooding, the airport was shut down, but with a few dry(ish) days things should be back to normal.
