If you any ideas, please help me especially if you already had a child before

Ja
We decided not to tell any of our family or friends until we are out of 1st trimester. Had a MC last month which was horrible but I have a son (previous marriage) and I want to know how to announce it using him. If anyone has ideas or pictures to show, that'll be great. It's so exciting and my 1st pregnancy was horrendous, due to being cheated on and left the whole 9 months. I want something to remember in a positive light and I want to use my handsome 5 year old in it. Thanks ladies😘
