I have one and my daughter hated it! I think the last time she was in it was at 4 months old! I'm hanging onto it in the chance #2 will "not-live-without" one...if I ge tthe same reaction I'll sell it. I have a friend who's child lived in one since birth, the only way he'd stay calm and/or sleep until he learned how to self sooth.
Now my model kinda sucks, its not very deep-seated and the space between the legs and snack tray option are very small. My sister-in-law just got one recently and its way better! Funny how things change in just 2ys.
