Quickening

So we have movement.. I am about to be 16 weeks and for about the last week or so have had some fluttering. Wasn't sure at first, but pretty sure it is the bean making him/herself known. It is reassuring, as it feels like it has been forever since my last apt. Our next apt. is this Friday at 8am, so that Brian can go with me, so he and Eli will both be able to hear the heartbeat. I have been trying to negotiate with Brian about finding out the sex of the baby. You may remember that we had an agreement not to find out this time because we did find out with Eli. Well most of you that know me, know that this just doesn't work for me. It will make me crazy.. So I have offered to let him choose the name, if we are able to find out the sex. I think that is reasonable, but I don't think he is going for it.. Don't you think Eli would benefit greatly by finding out in advance if he is getting a brother or sister??
