Twin 1 Year Olds - TSA

Hello! We’ve traveled with our twins as infants and just rolled them in the stroller through security. How does it work with 1 year olds? Since they’re older I wasn’t sure if they just walk through with us or we have to carry them? Can we keep them in their stroller?

If you have any other tips for getting through TSA with 1 year olds, greatly appreciate it!
