Anyone use this? How young of a child have you used it with? We are expecting #2 in April, DS1 will be almost 22 months old. Have heard not-so-good things about the rumble seat, and better things about the piggyback board. Just wondering if my not-quite-2-year-old will be able to hang? I think so, just wondering. Thanks.
