Hope someone can advise......here's the problem

Just bought my mother in law (aaargh) a DVD player and a Freeview box. She has a Sony Tv with one scart socket and a VHS video hooked into the TV via scart.

How on earth can I get these three appliances to hook into a single scart input TV whilst allowing her to use the VHS to record TV/Freeview......I'm stumped...

Thanks for any help
