Bubbles! Toddlers love playing with bubbles, chasing them and popping them, or just watching them fall. Bubbles can usually cheer up a forlorn toddler. Just be sure to have a towel nearby for bubble "juice"!
For the toddler room, make sure there's two (or more) of each toy - two scooters, two play telephones, two baby dolls, etc. This solves a lot of problems, as children this age do not always understand the concept of sharing.
Friendship bracelets! Children of all ages love this, even the boys. They can make bracelets or keychains or anklets or whatever they please. When teaching children this craft, I always begin with the twist friendship bracelet. Then I move on to stripes, then chevron, and then hearts and more! Make sure to stock up on friendship bracelet string/embroidery thread - it goes fast!
Make sure that if your daughter is wearing a skirt or dress that she wears shorts too! Chances are she will be rock climbing, using the monkey bars, doing cartwheels, dance routines, etc. Plus, its just a good rule of thumb.
This one just cracks me up:
Chicco Rocking Eggplant
It's a rocking eggplant! It is designed for toddlers, and it allows them to sit and rock - on a giant purple vegetable! Older kids also enjoy it too - they use it to scoot around in a weird, flying eggplant sort of fashion. Also, this large plastic vegetable also has a face with a nice friendly smile. And a stem that is removable for some unfathomable reason.
Well, that's all I've got. More Pinspiration coming your way soon!
