Help! Two year old won't stop treating armchair like a bouncy castle.

[Mummystootired]

She's been doing this for a couple of months now and it's driving me round the bend. How do I stop her doing it? I'm worried she will fall off and hurt herself.
I have tried lifting her off but she just goes back and does it again.
Another problem we have is she keeps hitting people.
Can anyone suggest anything?
or is anyone going through this too?

I'd just let her bounce! Unless she might break the sofa. Ds ( 2.2) loves to jump on the sofa :) if you're worried but some cushions on the floor. As for the hitting, we use the naughty step with some success, but he's just starting to understand emotions so I'm able to explain that it makes people sad when he hits them, which does make him think twice about it at least.
