I HATE HIGHCHAIRS!! THEY HATE ME!! They are all the daleks of the real world.
I have two from M'care, the cheapy wooden thing with tray and one of them is on its second round. They are as clean as I can get them (DTs have taken over the 'feeding') but the plastic seats are coming to bits now. I refuse to buy any posh ones because they all end up smeared in caked on bits of food mixed with yoghurt and the harnesses NEVER COME OFF TO WASH!
I actually love highchairs. They are a real marker of progress.
I will have a symbolic torchlight burning ceremony when we part.
