We'll be spending 3 days in Portland with our 2 1/2 year old and are looking for things to do that would be fun for all of us. I know about the children's museum, the zoo and OMSI (although not sure if she is too little to have fun there). We're definitely checking out some of the bigger gardens but wondered if there are any 'must see' attractions that she would enjoy. I heard somewhere that there's a park that has a water feature for the kids but can't remember the name.
Also, any recommendations for restaurants or neighborhoods to take a stroll in with a child.
