Hi...I have a 3 year old who usually wants to walk and a baby on the way. I have seen these stroller attachments that the toddler can stand on, I think they are called boogie boards? Does anybody here like them and where can you get one? Do they attach to any stroller? Is that my only option? I have heard of the Snap n Go Sit n Stand, but I haven't read the greatest reviews. While I'm asking, should I go with a Graco travel system for the new baby since everyone loves the Snugride, or is there a better way to go? Thanks so much for any advice...it's been awhile for me as far as the infant stage!
