2 kids or 3....

So, I think about this almost constantly. We now have 2 boys. I'm undecided to try for a 3rd. I don't want to be selfish and say I want my girl! I know I don't decide that. We are in a different situation now than when we were when we got married and were starting a family. Now, we have our 2 boys AND my brother. So it's like having 3 kids, yet my brother will be out of the house in not too many years. I don't want to decide if we have another kid just because we have him living with us. Because I don't want to end up down the road regretting not having another child. Then again, we don't know if we could afford another one. The reason that I'm thinking of this nonstop is because I wanted to be done or be pregnant by the time I am 30. Well...I will be 30 in a little over 4 months. So now is the time to decide. So if you are out there and reading this...if you have 3 kids..how did you decide if you wanted another after your 2nd? Did you have 2 of the same sex and were trying for the other? Or maybe you just like having a house full of kids, I'm not sure. I think I am done rambling for now. I think I just have baby fever and it's taking over my brain!!!! LOL Have a good Wednesday everybody!
