Maybe Babies'r'Us has changed since I was last in there five years ago but unless you're Gwenyth Paltrow, I think they have a range of products from low quality to very good quality and my anecdotal evidence is based on using them for two kids.
Also, taking your kid for long walks in a stroller is so fun. I did love doing the same with the (unbelievably overpriced) Baby Bjorn, and the backpack carrier, and the sling, but I'd take my kids for 5-mile walks around the city and the stroller worked very well for that.
I'm against the co-sleeper and the whole idea of the babies sleeping in the parents' bed. I understand that it works for some people, but both my kids are amazing sleepers and I attribute that largely to their being comfortable alone in their crib, racecar beds, big boy beds, and now regular twin beds.
