Wonderful product!
Style: Body Wash & AOO - Fragrance-Free
Absolutely love tubby Todd! Great for my son’s sensitive skin. No eczema flare ups. The all over ointment clears every little thing up. Expensive but worth the price. We love all tubby Todd products.

3 year old reacted poorly to all the “clean” local brands and this was recommended by someone! Highly recommend! Took away her dry skin, irritation, and rashes that the other brands caused!
