I just bought DD (she is about 4 months old) her first high chair. I just put it together and am already having second thoughts. I bought a high chair that was not a convertible type ( meaning goes into booster later on). I figured we would get good use out of this, and it was inexpensive, and when the time came we would get her a booster. Now I am wondering how long do kids sit in a high chair for?! Any thoughts or advice is appreciated. TIA!
