My mother purchased this high chair for me and I a not too sure I like it for my sons age now. He is 14 months. I have been sitting him in this since about 4 months. I am now starting to think that he isn't wanting to sit still in it because he doesn't have very much room between his crotch area and his back.
Once we got one of those blue portable plastic chairs - they come with a tray, you just put them on a regular chair, for our older son, we got another for our younger. They were totally easier than high chairs. Both to strap in, and to clean. And 5 bucks at rummage sale.
plus we can bring it other places as it is portable. The pad comes off and goes in the wash (even though you don't want to do that...put it could be wiped too) and this can be used from high chair to booster seat. It folds flat for easy portability. Plus it takes up no extra space as you attach it to a chair you already have! And no worries about the crotch area... it's just straps.
