It's funny b/c I too wanted a tiny.
I am so thankful mine turned out to be a little bigger than tiny.
TJ is 7lbs - Roxy is about 5.5 lbs.
I look at TJ and he is just the perfect size (even if he were a little bigger, I wouldn't care!), especially if we were to have children. I think it is better for us that mine are not tiny! JMO
I think your little guy is precious. Even 'if' he were to reach 10 lbs, to me that's small
Best of luck!
