Jumper toys for 4 month old

[Tigger001]

My 4.5 month old DS just wants to be on his feet all the time, he has strong legs and can nearly blooming stand unsupported. We have bought him a jumperoo for Christmas but I don't think his legs are long enough to actually use it "jump" but we will use it for him to play and be uright.

Does anyone have any suggestions on toys or ideas as I can not keep holding him up and he only wants to be lay down or sat for 10 mins at a time ??? Any suggestions would be great

I put a couple of big books under the jumperoo when they were too short

Put a big cushion or bean bag under the jumparoo

Walkers have settings to lower the seat so you could get one of those (second hand as your LO won't be in it for long)

One of them door bouncing things

I feel your pain, advanced kids are lovely until you have to entertain them 24/7 when everyone else's baby sits nicely like they're supposed too
