Scoop your poop somewhere else
Shopping trips with babies are tricky beasts to manage as a new parent. You have to make sure that you’ve remembered to pack around 1million things, including diapers, wipes, spare clothes, snacks, and the proverbial kitchen sink. Usually, the baby will have filled its diaper just as you’re about to leave, so you’re already late.
Occasionally, you’ll have to deal with another full diaper whilst you’re out shopping. Usually, though, you’ll use one of the restrooms stores tend to have. Most of them have changing tables, but even the ones that don’t will have space somewhere in the bathroom to change the baby. For future reference, changing the baby on a display table is not a suitable alternative, no matter how desperate you are.
