I read this today on my What To Expect pregnancy tracker app. I find it to be quite accurate.
"By now you've noticed her breasts are enlarging ... to heart-quickening proportions... But always ask before you touch and touch gently when you get the go-ahead. Whether you're just looking or touching, enjoy them while you can - in seven months or so you'll be sharing them with someone who craves them even more than you do."
The full quote even suggests that "a look but don't touch policy" might be in effect. Haha. I'm loving my pregnancy apps. I really like being able to read a quick note about my baby in the middle of a long day.
