Thing about your second pregnancy is, your body already knows what's up.
I am at week 16 and fortunately out of the first trimester. Three more weeks and we have our ultrasound to determine whether Lucy is having a baby brother or sister!
I should have another post up soon about Lucy. Right now it's a word a day with her; her most recent one is "bottom" ("bompom"), and she enjoys rolling her giant stuffed sheep over and pointing to its bompom.
