Mickey is 6 months and 10 lbs! We keep thinking that he will slow down, but he just keeps growing, and growing, and growing..... At this rate, we might be right up there with Wee Wee and Maggie May May (who are gorgeous btw!). It's okay... we actually opted for the biggest one in the bunch. The breeder swore up and down that he wouldnt be over 6 lbs "if that" she said... just goes to show you.
I think Mickey was just under 5 lbs at three months. I think the rule of thumb to figure out their fully grown size is to double the weight @ 3 months. Dont know how accurate that is though.
When I get a little girl I am going to try to go on the smaller side (when I say smaller, I am talking 6-7 lbs) this way I can have the best of both worlds. I love my little teapot though!
