Just catching up. Belated Happy Birthday Lyra!
Jolls glad things have settled down - good luck for scan tmrw.
Ice agree with everyone else - think the panic is natural. Like all of us who will be adjusting to families of 1,2,3,4 and 5, you'll probs feel overwhelmed a bit at start and wonder how you'll ever manage to get out of house at decent hour and then it will gradually click into place. My DS will be 2 and 3 months and every so often I have an utter panic day!
On boobs, I agree with whoever said it's luck of the draw. My friend had massive boobs which just disappeared after breastfeeding - she is 3 cup sizes smaller than her pre-pregnancy boobs. Others are less affected! A bit like stretch marks I guess!
