Well, got you reading anyway .
My mum got my son an inflatable see-through cylinder with rattling balls in it when he turned 6 months (3 years ago). I think it was supposed to help the baby sit up/be more active as well as being a fun toy. Anyway, ds destroyed it eventually after getting a lot of fun from it and I would like to get a new one for dd.
Mum can't remember where she got it from although given her normal shopping habits, I would guess elc or John Lewis. Neither elc or John Lewis stock any such toy after all this time. Does anyone know where I could get another from?
