Head Poncho this sounds like a lovely thing to do. Personally being a LTTTC and the pain of missing out on all those little things that come with being a mother it would be wonderful to receive something as 'normal' as a mothers day card IKYWIM? Your friend is a mother to this child and for you to acknoweldge that will probably mean a lot to her. I do not think in any way are being insensitive to her infertility.
