So I have retired our baby carrier and my husband found this saddle back back that has ankle straps and a seat lol. I told him he can wear it i'm not sure about it. It's awful trying to push the stroller in the snow so I have been using the sled but there's no room to carry stuff just my daughter.
Here's a link to see the saddle back back. it's kinda neat but I don't think i'll use it but I know my husband will.
