Hi Jessica,
Isn't that such a fantastic feeling? I can still remember waiting and trying to figure out if they were getting more sensitive but then it was clear, this is what I had been waiting so long for, wow. And then they start growing and you watch and feel them and bump into things and groan and still love it. One side will grow slightly more than the other and they may trade off which is bigger, and you find it time to get a larger size bra........yes it is really fun. But let me tell you, while boobs are really really fun, soon, your emotions will begin showing up. Feelings like you have never had before will drive you to tears, at least they did for me, starting about the three month mark. For me, I love my boobs (somewhere between 36 b and c at 15 months) but the emotions, empathy and compassion have become what it is all about, I might even be willing to give up the boobs under high pressure but the ability to feel and cry, never!
Enjoy the journey but hold on, it gets really wild! - Anne
