Which sunhats do you recommend?
We use a standard sunhat from Pumpkin Patch, or sometimes a cap.
What sunscreen is safe for baby/toddler, but still effective in the paddling pool say?
We love the Hawaian Tropic 'Baby faces and tender places'. It is spf45 and doesn't seem to react with Sam's ezcema. It does need to be reapplied after swimming though.
What kind of sunglasses does your baby/toddler wear?
Baby Banz. Fantastic as the elastic strap holds them in place.
Where can you buy those towel things that look like a poncho (ie they are made of towelling material, but have a hole in the middle with a hood attached to the hole - kids wear it like a poncho at the beach etc)??
You can get them from the warehouse, bed bath & beyond etc etc. Basically most places that sell linen/towels. Sam has one, but doesn't really like to wear it much to be honest.
I hope that helped a little
