I have not read other replies on this thread so i hope i am not repeating anything.
I got a stroller for the sole purpose of taking them all out doors at the same time. that sure didn't happen too often. mom , dad and 4 babies in a stroller.
that stroller sure did come in handy when we had our vet visits tho.
it kept them all together and off that dirty floor.
go ahead ...use it and smile real big.
