Okay, confession time. I have only one child with special needs. Only one who needed a "special" chair at the dinner table.
We have three.
When Will got his - paid for conveniently by another funding source - my oldest wanted it. Sat in it. ALL the time.
She got a Hipposmile for her birthday...similar model, different manufacturer. The quality is a bit less, but it was $100+ cheaper.
My littlest came home. We decided to use some of her birthday money and money left from a shower for her own Tripp Trapp.
Check them out. Will doesn't need a ton of help with positioning, but he does have low tone and needed some place to put his feet to "ground him" while eating. We LOVE ours.
