I agree with Crystal- pick a time and do it. When my kids were that age, I would wake, feed, pack in the carseat and head out. I found that by the time I burped, changed and got stuff together, the awake time was just about over, so the baby would sleep in the carseat, hopefully during the drive and the errand! If I was feeling brave, I could stretch the errand to a few hours and do two Easy's, KWIM? I think as long as you don't do it every day, your lo won't associate sleep with the carseat. Also, I would try to choose whichever nap was their weakest, so they still had strong naps at home in their bed. You'll find as you get older it gets easier and easier to take them places. Until they can ask for things, that is! :wink:
