Re: Calico critters
They are super cute and if your son loves them I say go for it! We only have a couple sets but they are very nice quality, much higher than your average mass-produced plastic. We only have a couple sets and my DD plays with them in her non-Critters dollhouse. They come with some small pieces but when I gave my DD the dining room set last year I held the plates and tiny things back until she's older. I've seen the sets on Amazon and other places for buy-one-get-one-half-off sales. Barnes and Noble carries them too if you can find a coupon for them. I know Target has a "Woodzeez" that are cheaper but not sure of the quality.
