Joovy Noodle Multi-Sport Helmet XS-S

if you have the space for this, I could not recommend it more, but only if you can get it on sale. ours is almost 2yo and has survived dozens of kids and parties. it pays for itself in entertainment.

i prefer bike helmets with the front visor to reduce the chance of face scrapes and keep the sun out of their eyes. these are pricey - i target below $60, usually during the big sales.
