Hard situation. How to announce baby #3??

Okay. Long story short.

This is my 3rd baby. I have two boys. One who we lost almost 4 years ago. It’s hard to just type that. We lost him in an accident when I was 8 months pregnant. He was 2 1/2 years old. Loosing him completely crushed me. But I was 8 months pregnant with my second son. My husband and I stayed strong for him. We made sure he didn’t feel/see our pain and sadness. But not a day goes by that I don’t think of our son who passed. We’ve been trying to get pregnant for 2 years. We’ve miscarried 3 times. We have had an ultrasound and could hear the heartbeat-130 🙌🏻🙌🏻🙌🏻

We want to announce around Valentine’s Day when I’ll be 12 weeks. But i don’t know how. I want to include my son that I lost in the announcement. There are so many people that call my second son an only child but he’s not. I’m just not sure how to announce it, include both my sons in it, without being morbid or making people sad. I’ve racked my brain and thought maybe some of you ladies would have some ideas. TIA!
