My SIL bought one for her bub when he was about 3 months, and well, lets just say the novelty wore off quite quickly
I think they'd be great if they were made a little heavier at the base, and if they had some sort of fabric over them. The ones I have seen are sort of rubbery and I think they're get a little hot and sticky in summer.
yeh maybe it is a boy thing cos i have to agree with Lorirae - we had the exact same problem, even with the tray.. i have already past it on to a friend to use.
