I am assuming your friend knows you were TTC. I had a similar sit with my 1st and 2nd, close friend had been TTC and on IVF for about 3 years. We lived close and they loved being "auntie and uncle" to my DD(they got in as much practice as they could), luckily we both conceived at approx. the same time with our DS's so you can imagine how happy we both were. You just have to remain supportive of her needs and feelings and everything will work out.
