Thanks.....we had them natural this time. I will look into the meds you are talking about. If we end up with boys this time then we will let nature take it's course the next time around. Congrats on all of your boys sounds like your doing something right, lol. I can imagine why you want more girls.     Congrats on the twins! We are also going for twins our next time around and did with our first set. I took the meds on my own and saved a fortune. It was only about $160 or so for the month we conceived them.   As for sex selection, I also joke that if we have boys the next time we conceive multiples (I'm pregnant with our 4th son and only have one daughter...twins would make 6 boys to 1 girl!) that I'm having his sperm spun! I haven't looked into it much, but I guess they spin the sperm and the X and Y seperate and they can inject only the type you want and fertilization happens naturally inside the woman after that. (My luck they'd inject 10,000,000 Xs and 2 Ys and I'll get twins boys!;)) It's a whole lot cheaper than an entire IVF route. Plus with IVF, the woman has to take meds, have the eggs removed painfully and then the embryos injected into her uterus painfully. Spun sperm is injected into the vagina without pain.  Were your twins this time natural? You said next time you'll have a doctor give you twins so I was just wondering if you did this time also. Try out the sleepless nights the first year first, then see how many you want at a time next time!:D I'm a glutton for punishment so it didn't scare me off to wanting twins again, but many parents get smarter after experiencing it!:p
