Reply #24: I had 2 kids 14 months apart, and I sometimes pushed them in a stroller even after they could walk

It's faster. It's easier. It's just more efficient. Mom's work hard enough. Otherwise, you are dealing with kids melting down, whining, running off, getting tired, literally dragging their feet, darting around, and don't even get me started on parking lots -- all the while trying to shop or run errands or get somewhere. It's even worse if you have a 4 or 5 year old with you, walking alongside you, on top of the other 2 in the stroller. Trust me.

I'd still be pushing them in strollers if they made the strollers big enough! - Kidding! :P
