I am considering second baby, DD1 is 21months. Now I am not small bobbed to start with 30G, but was huge during pregnancy and until baby was about 10 months.
Of all the pregnancy related issues you could be anxious about the huge boob thing is my concern. I was at the limit of maternity/bf bra sizes, 32J and even though I fitted into my jeans 3 weeks after birth it was almost a year before I could do up some shirts! Couldn't sleep without elasticated dance-style tops on to hold them in place. Just not even funny. Their size actually freaked DH out.
Do your boobs always get sooo big the second time you get pregnant?
