I'm the youngest of 6 and I have 14 nieces and nephews and 3 great nieces do it's nothing new in my family either....so when I tell them I'm going to make copies of the ultra sound p pictures in christmas cards and have them all open them at the same time :)
I think that is a cute idea! We were considering sending ornaments, but weren't sure how well they would ship in the mail; all of my siblings live in other states, unfortunately :)
I bought a photo frame that said " I'm lucky to have grandparents like you" and put u/s pic in it. I've never really seen my dad cry until that day:)
I think it would be cute to make or have engraved a custom ornament for each of your main families (each of you parents households, each siblings household, etc) with the month of your due date & 2012. You should be 9-10 weeks by Xmas, right? It is a personal decision, but I told my family at 9 weeks because we had our first ultrasound & everything looked good. And most of them were guessing we were expecting anyway. ;-) Congrats to you!
I AM NOT TRYING TO SCARE YOU (Stupid computer) SORRY.....
i would say wait till you pass your 12 weeks. Many reasons but the best one is possible of early miscarriage i am trying to scare you and i pray your baby and you grow fine. just to be on safe side wait. :).
