I have a 2-1/2 yr old and a 6 month old. I've been ordering online from Peapod since I was 8 months pregnant with #2. When we actually have to go to the store I put the toddler in the seat of the cart and wear the baby in the Bjorn. Unless of course the baby's asleep, then the entire car seat goes in the cart, the toddler goes in the seat, and the groceries go in one of those  hand-held baskets that I put at the bottom of the rolling cart.  See? Easy :-)
