Ok so I have 2 boys one five and one 2 who will be 3. I am pregnant and go for my first sono the same day my sons who gonna turn 3 birthday. What I was thinking was putting the picture of the sono onto a birthday card saying happy birthday with the due date. I have to include my other son to so I was thinking of having a sign saying been there done that. And a sign next to the birthday boy saying I get to be a big brother for my birthday? Then the card with the sono and due date next to him and announcing it that way. Or should I wait a diff day to announce it???
