I feel like my 10 MO is too grown up

Jessica • My rainbow baby was born on 7/25! 1 MC in May of 2014. PCOS sufferer, conceived without medication, I used plexus!! :)
I feel like my baby is growing up too fast, he just wants to go! He's 10 months old and already walking, he sleeps perfectly through the night in his own bed and he's saying about 3 words. 
Maybe it's because I have PCOS and I don't know if I'll get to have another child, but I really feel like my baby just grew up too fast! I realize he's still a baby, but you know what I mean! 😀
