At 3 months, we let Zi try the exersaucer because she preferred standing up most of the time she was awake. She hated the bumbo or infant seat so we skipped it and let her stand. Within a week, she learned how to pick up various toys and press different buttons to make sounds, and turn the seat around to reach for an item. One of her favorite things to do is to pick up and make out with the turtle (as pictured)… The exersaucer pictured was the one we bought for Emma, and the same one that was passed down to Hong & Seph. So, this bad boy was one great investment. We bought it when Em turned four months, but Zi seems to be enjoying it at an earlier age.
