Hey all. I was wondering if anyone has this chair that has a bigger baby. Eli is 5 months old and 20lbs. He has very chubby legs. I read that babies with bigger legs aren't comfortable with the chair. Can anyone confirm/deny? I think Eli would love the Bumbo chair but I don't want to invest 50 bucks only to find out he hates it. No one I know has one! Thank you!
