I am no expert on babies – I just have one. I’ve literally had to buy nothing so far for my son when it comes to head to toe body wash, shampoo, and lotions. I recieved about three years worth of it at my baby shower. Babies are little (duh), so a 15 oz bottle of lotion will pretty much last them until they quintuple in size (I never in a million years thought I’d ever use the word quintuple). So to get to the point, one of my favorites is Johnson & Johnson’s shea & cocoa butter baby lotion. It smells nice and it gentley hydrates baby skin (your hands too). This large bottle is under $5 and I totally recommend it.
