As a momma of 4 who just went through this exact situation several months ago I totally know how your are feeling!!! I'll be honest I shed quite a few tears, but I've come to realize that God will only give me what I need, he will only give me what I can handle and apperantly God has decided I needed another little person to love and care for!!! Even though I thought my family was done growing he KNEW that it wasn't!!! Now I'm just 10 short weeks away from meeting my newest angel and I CAN NOT WAIT!!
I wish you all the luck in the world and a very happy, healthy and SMOOTH 9 months!!! Oh and heck I'll even throw in a few sprinklings of pink dust

Good luck Emmy!!! Just keep telling yourself...the more the merrier!!!
