This is an absolute essential in our house. After memories of fighting diaper rash for months with our son, we started using this from Day 1 on our daughter and she has yet (at 5.5 months) to develop a single case of diaper rash (despite having eczema), except for the one weekend we spent away when we forgot this - we couldn't find it in their local store, so picked up a tube of Aveeno zinc diaper cream. By the time we got home on Monday, she was sporting a nasty diaper rash! I can't recommend this product (and the entire line) enough! We use the kids' and adults line and love every single product. Plus, it's Canadian!
