For the babies' birthday, we purchased the Step 2 Choo Choo Wagon, which was highly recommended by other triplet moms. Other moms had warned that the company had been on the verge of discontinuing it, so we bought it early and it has been in our garage since January! We finally thought they were ready and set it up in July. Our original plan was to just use it for the babies, but several problems hindered that plan. Drew loved it and it never occured to him that he wouldn't be able to ride in it. Additionally, Emily couldn't sit on the seat, so she wouldn't be able to ride in it. We solved both problems by buying an additional flat bottom trailer on craigslist(Thanks Uncle Evan and Aunt Mary for picking it up for us!) and securing a Step 2 toddler swing in it so that Emily could join her siblings in her cozy caboose. The trailer can be attached to the second or third car, so Carter, Brenna, and Emily can go for a ride with or without their favorite conductor!
