I'm expecting triplets and have an older child. My husband will be away most of the day and we don't have a vehicle all the kids would fit in anyway. We literally bought a sedan two days before finding out it was triplets, we had to move to a larger apartment, and we needed a washer and dryer to be able to cloth diaper so the budget is shot for now. This means I'll be doing a lot of walking and public transportation with 4 kids because we don't have anyone here to help. It's required to be able to fully collapse the stroller for the buses here and I couldn't find a triple stroller that would work with so we have a double and I'll be wearing the third baby.

Most of the bags I've seen when searching for extra large diaper bags specifically say they only hold two bottles. That's not going to work. Even a trip to Walmart involves two buses, the subway, and a decent walk so it takes hours.

I have another concern though. My son will be 9 years old when these babies are born. He has autism and isn't yet able to be fully toilet trained. He can carry a small bag with his own snacks and water but he has a congenital heart defect and can't really carry much more than that without overstressing him. Which means I also need to carry a spare pair of pants and pullups for him.
