bath support for 11m old in big bath?

[choolie]

Is there such a thing? I just seem to find bath supports for newborns, but now that DS is in our bath, he's such a wriggler, a little seat would be useful - we currently sit him on a flannel, which helps somewhat, until he moves it, or tries to chew it .

Anybody recommend one?
TIA

Sorry to be dim but if he is sitting up unaided why do you need a support? if you are worried about him slipping get a rubber bath mat?

We have this one.

Assuming he can sit unaided I wouldn't bother - just get a bath mat. DD2's a wriggler and LOVES a good wriggle in the bath!
