Alright Mothers: I'm standing in BJ's staring at Huggies and trying to compare the two varieties they offer for my 4 month old's heinie. $39.99 for a box of either 240 of "Snug & Dry" or 186 of "Little Snugglers." S&D seems to be bragging about 12 hr protection while LS is for sensitive skin. Is that correct? Am I missing anything?
