baby borrowers

[Penny]

as the last series was on each week, i assumed this one was too (and after i watched the first show it didn't say when it would be on next) and then the other day i watched the one with teenagers and realised i'd missed all the others!!

I was a bit gutted because i really wanted to watch the ones with the babies and the kids.

is there anywhere i can watch them again?
I've checked all the tv schedules and they're not being repeated on any day.
I saw the one where they moved into the houses, the one where they had the teenagers, and the one where they had the old people. i really wanna see the others! any help?

thanks
