Telling our son 😬

So my husband tells me this morning that he wants to tell our 10 year old son that I am pregnant!

I am only 5 weeks along and to me that's too risky! But my husband refuses to tell anyone else and said he wants our son to be the first to know. I understand that and he is definitely on my list as one of the first to know, but I would be more comfortable at 8weeks telling him.

What do you guys think? How long did you wait to tell your kiddos?
