I don't think it's a matter of it being wrong to make a quilt for a child, I think it's wonderful. I don't think that every child that uses a quilt will have a problem. But even if one in a thousand or even a million does, what if it's your child/grandchild that is that one.
Even if it's considered SID you'd still be wondering if you'd been wrong not to warn the mother about using the quilt in the crib too early. I was raised Catholic, I feel guilty about everything so I wouldn't want a quilt of mine anywhere near my son's children (if he had any) if I thought there was the very SLIGHTEST chance that it could be a problem.
