Let me put my flame suit on first
I loved my double snap n go. It enabled me to quickly get out to the grocery store to grab essentials in a 30-min door-to-door trip without waking the babies up. I know about the whole "don't leave your infant in the infant seat if you don't have to" but with multiples...I say it's allowed for a 30 min grocery store or other errand trip a few times a week when babies are newborns/infants and you are desperate to get out of the house to buy coffee, and you need to do it quickly and easily between feedings.
OK, let the flames begin!!
