I dont understand..do you have a car during the day or not?? If you have a car, then you load them up and go get your son, simple as that. They may or may not be happy, could per chance even cry some, but your son has to be picked up. As for the other errands, while I dont have twins, I have 4 kids under 9, with one on the way, and have taken them out or the kids I babysit out many times. I would say make sure they have both been recently fed and changed, pack a good diaper bag, and go. You will eventually find that it was not as hard as you were afraid it would be. Good luck and have fun!! ~A.~
