I LOOOOVED my swing. She grew out of it by 6 months but until then, it was her favorite thing, she napped so so well in it and even when she was awake she'd be completely content in it.
I'm still using our baby tub (the Whale of a Tub), the pack and play and the diaper genie. Except for the crib sheets, and toys we're not using anything else from my shower gifts that comes to mind - I'm glad I have a shopping cart cover but I haven't used it very much yet because I put Livi in the stroller when we go shopping. I'm also glad I have an Infantino carrier, but again, I don't use it much. I'm happy I chose a good one but a less expensive model than the Baby Bjorn/Moby wraps I was looking at for the registry.
