CONGRATS!!!!!!!
4 isn't that big to me, i already have 4 and 3 step kids and just found out im pg with another one, so that will be 8 lol I agree with Trish, the government want us to have more babies, we should be applauded for it, not given grief by people that it really has nothing to do with, i'm not asking them to look after it for me!!!!
Anyway, i hope you have a H & H pregnancy, and enjoy your large family, life is never dull !!!!!
