We just moved from Brooklyn (walk/stroller everywhere) to suburban NJ, where we are driving everywhere. Loading three kids (4.5, 2.5, and 11 weeks) into my SUV takes me awhile since I'm new to it, but it's not that big of a deal because we're safe in our (heated - hooray!) garage. But unloading, particularly in busy parking lots - yeeeesh! Not good.

Any tips? Right now the main place I do this is school, so I've just sent the big girls to stand on the lawn directly in front of my car while I get the baby out. But in places like the Target parking lot, this isn't really possible. What else could I do? Stick them in the trunk/passenger seat while I unload the baby? Or do they just need to learn to follow the "both hands on the car" rule (my husband tells them this) better?

Advice appreciated!
