As we do in the Netherlands, we congratulate everyone. So happy birthday with your boy .

And its both your time. Yes its his birthday but you are also important. And later when he looks back on this will he remember if he got a made card? Maybe?

My mum did everything she could for her children. And more. The best moments in my opinion where when she did something for herself. Your son would never want his mum to break or crack under pressure she gave herself. He never would.
