What to get a 4 year old for birthday? ( & nearly 2 girl, and 5/6 boy)

[LadyOfWaffle]

Friends DSs birthday in May and I really don't know what to get. He is DS2 so they have alot of toys etc., and I want to get him (them) something that won't be at the back of a cupboard in a week. Something for them all would be good (I thought for the garden?) but they have a playhouse, trampoline, slides etc. already. Budget I guess max of £50 . Thanks so much if you can give me ideas

£50 is a substantial budget, would it be an idea to speak to his Mum or Dad about he might want / need? Wouldn't want to waste that kind of moeny on something that will be forgotten about.

A basketball net might be a good idea
Maybe like this

I asked his dad who said he was into Peppa Pig and Toy Story but as I said they have alot of toys, so just messaged him & asked about something for the garden. I hope he isn't shy about telling me if they do ant something!
