Yeah, I know the math doesnt add up... Anyway, we just bought a double stroller and planned to bring it to Disney with us. We have three kids ages 5, 2 and 1. Originally we planned on using the stroller for the younger two kids but I'm wondering if we might need something for our DS5 as well. I don't want to bring a stroller only to find out that we didn't need it but I also don't want to not bring something and find it to be a big pain. Should we just try to swap kids out of the double stroller (it's a sit and stand one) when needed or what?
