So we decided that convertibles for the twins was best and would help us save money in the long run. We do not have a stroller yet. As we will be baby wearing when out and about. My question is. What if one of us are at a meeting or something with both twins. Do you hold them both at the same time? What do you put them in? Is there something I can buy to put them in thats not and infant seat? I totally wasn't thinking about this. Help!!!
