Back to my brother and others who are the first born male. I am sure that the first born is surprised they are sane. This child is the one that will set the stage for all that follow, that's what parents think, but we all know that as years go by parents change views and procedures. Often what they did was kind a crazy and maybe confusing. This child lived through it and so did the parents. Now the parents looks at the child and says, what a great kid, even with everything we did to him.
I designed a card that give the first born a little notification that the parents know how hard it was. Now some of those children have children themselves and will understand the card and the thought even more. I hope you like it.
