Query: Best baby item we have!

Our baby boy is now 10 weeks old. He had a tough first 6 weeks, allergic to proteins in my breast milk. The only thing that would soothe him enough to keep him asleep for naps has been this glider. We have gone through 2 sets of batteries so far(4 D size duracells), but he is in this for about 4 hours every day while he naps at the fastest setting with music and mobile going. It does fold up, we have transported it with us several times. The mobile comes off to make moving it easier. He is now 16 lbs and the glider moves just as well as it did when he was first born and 8 lbs. Only wish this had an ac adapter. Can not say enough good things about this glider!
