I'd have to say it would be my stroller (Bugaboo Bee) and maybe this Bloom Rocker.

I tend to buy higher end things (baby products or otherwise) if the quality and looks is worth it. Sometimes it's not that worth it but I want it anyway.

What's the most expensive or luxurious baby product you own?
