Morning 3rd Tri Girls. Quick question from a (clearly) first time Mom: I've been told Aquaphor is a must have as well as Butt Paste. I was also given some Desitin and told it was a must have. So, are they all for the same purpose? To treat diaper rash? Or are they different? I'm in 'over-prepare' mode and my changing table kit looks like some crazy 'Price is Right' product placement game. I'd appreciate any words of wisdom here.
