Registering is a pain!
Mentally, and physically! When we were registering at Buy Buy Baby, my feet were killing me by the end, and now deciding on a retail place, as well as if to double up and mention I'm registered at Babies R Us too, when I really, really prefer Buy Buy Baby's stuff, is just very taxing mentally/emotionally!
Besides, I've done the registry thing with my wedding shower, and like... no body gave a crap what I registered for. Maybe 2-3 people, and those were obviously my favorite gifts. So I'm a bit jaded by the process thanks to that.
Hang in there!
