Hi J.,
I'm a mom of 3, and I put my kids in the high chair as soon as they were able to sit up. The one I have has a 5 point strap, and it helps the baby not slump over. My advise is get one with a plastic seat (not cloth) because it's much easier to clean. Some prefer the cloth ones because they can go in the washer, but I have enough laundry to do without having to wash the seat all the time. Babies drop everything! Also I didn't have to worry about stains. Hope this helps!
