Equipment recommendations needed please!

[NinePeedles]

Can anyone recommend a baby monitor which has battery backup in both the transmitter and the receiver? I need to have one that will work in a power cut. I don't need any visual monitor, sound only is just fine.

Also, recommendations needed for pushchair/wheelchair for a 5 year old?
It must be parent facing and have a 5 point harness, and have room underneath to carry heavy medical equipment. Current buggy on last legs and will be stuck without "wheels".

Also, what is a good buy after "littlelife" backpacks? (currently a lifesaver but only just fits now). I need something with a strap, as dc is a little bolter!
