Ds is nearly 5 months and quickly getting fed up of his playmat. I'd like to get a jumperoo type plaything for him but he needs to be properly supported, he can't sit up unaided yet and he's not one of those babies that has really strong legs. He's also bloody massive so it needs to take a lot of weight if we're to get more than 5 minutes use out of it.
Any recommendations would be greatly appreciated
