LOL, shouldn't you know better than anyone? I feel like I can barely remember what one-year-olds can do and can't do. A few ideas, if memory serves.
-self feeding stuff -I always love books -chunky puzzles -Gymboree bubbles because they're easy enough for toddlers to use and they don't sting when you get it in your eye. -Play doh -Chunky crayons or finger paints
Yes perfect. Bubbles, fingerprints and baby crayons. They still have the summer here to use that stuff. For A's bday we got a lot of big toys and I don't think that's practical for them. Creative supplies FTW.
