Collares de hielo

Choose to wear them against bare skin...with lots of squealing, or over your shirt for a cool, steady soak.

Repelente natural contra mosquitos (??)

Here’s what you’ll need:  essential oils (citronella and lemongrass are musts, I also like lavender or you could use tea tree oil or geranium oil for tick protection), 14 oz. bottle of witch hazel (available in grocery stores & pharmacies usually close to the rubbing alcohol), a spray bottle (or two–one for home and one for the diaper bag/car), a jar for mixing, and a funnel.

We used these essential oils:  citronella, lemongrass and lavender.   You could also use peppermint or cedar wood essential oils as well.
