My kids favorite products are from lush. This is body wash in jelly form. You can also pop it in the freezer or fridge for a refreshing shower. Also it’s sensitive on their skin.
Whoosh | Shower Jelly
Lush bubble bars. You can cut and save the rest or even just run under the water to create a bubble bath. All natural ingredients and the only bubble bars/bath bombs I allow my kids to use.
