Yep. We were given it when Ryan was almost 3 months old. He liked it right away, though we didn't use it much until 4 months when he had better torso control.
With AJ we used it at 2 months on the tallest setting
. I think he was born ready. He loved it.
Nate is just starting to use it. He's smaller and slower to sit up than his brothers, so he's just getting there, although it is on the middle height setting since he is also tall.
Since our's is 4 years old it doesn't have any flashing lights or gizmos. It's got a mirror and beads, and honestly I like it because he can sit in it and it has a tray all the way around for the toys he prefers. And his brothers can surround him and play WITH him.
Ryan used to sit and eat his breakfast in it when he was 9months-18months old.
