Start with the part that is verifiable
Separate the event you can describe from the motive or reaction you are guessing. For a message about how to congratulate someone on an adoption, use this factual base: name the milestone and, when you know it, the effort or meaning behind it.
Make one answerable request
Give the recipient one concrete question or next step instead of several emotional jobs at once. Offer warm recognition and let the recipient decide whether they want a call, visit, gift, or quiet celebration. Make the immediate next step clear enough that the recipient can answer without reconstructing the entire history.
Leave the recipient in control
Do not make assumptions about pregnancy, money, relationships, health, or what the achievement should mean next. Follow the person's lead on privacy before sharing their news or photos with anyone else. A clear message remains useful even when the answer is no or no answer arrives.
