I'm not much help since mine are a bit older. I try not to do it often. I try to do alot of errands when the big kids are at school or when Ben can watch them. Walmart has the carts that have the 2 seat thing attached to the cart. The big kids go in it, and Hannah goes in the other part. Otherwise the big kids walk. What about a double stroller, and then slinging the baby. Maybe by the time baby gets to big to sling you can work on Matthew walking. When Kalista started walking with me I had her "help" me push the stroller/cart. That way she was hanging onto the cart and I knew where she was. This is how I start all my kids out. Hannah has done it a few times, but I haven't pushed it since I haven't had a major "need" to yet. But I better get started on it.
