Infertility is a bummer

This beautiful boy needs a sibling. My husband and I have been trying for 4 yeas to get another precious child into our home. I have been doing IUI treatments, we have done 3 unsuccessful rounds and because of my "age" my doctor wants us to move forward with IVF treatment. However, I am teacher and my husband is in logistics and financially we just can't afford this alone. We are hoping there are people out there who understand and can donate just a little to help us with our goal of a family.
