My acid-reflux son loves this thing. If he's not in my arms, he's in the bouncer. With the exception of tummy-time and sleeping, my 5 month old spends his days in this bouncer. He has acid-reflux, and in his early days, this bouncer was the only thing that helped kee me sane. It's the perfect incline to help his acid to keep from coming up, and when he kicks his legs, the soft bouncing seems to soothe him. Now that he's getting older, he bounces it so hard that the bouncer starts creeping around the hardwood floor. If you stairs or a step, make sure your 5 month old doesn't have access to it when he's in the bouncer. Mine has been known to "bounce" his way across the living room hardwood floor. He loves swatting at the hanging animals and remains entertained for almost an hour or so when he's in his bouncer. He also gets a kick out of seeing how hard he can bounce it. Make sure to buckle your little one in, as particularly hard bouncing may make your baby bounce his way forward and out of the seat!
