My almost 1 year old hates her Ikea high chair now too. Its such a pain as I loved being able to drag it round the house and feed her while I was doing stuff like the dishes or cooking.

I've been feeding her on the floor when she stands up in her high chair (stoopid me cut the strap off when she was tiney as they were a pain to clean ) but MIL has a booster seat for normal chair that DD sits quite happily in so I'm going to try and get one of those and start having meals up at the table all the time.
