Before you pick a message, consider these three rules:
- Consult Your Son: If you aren’t sure how serious they are, ask him! You don’t want to send a “welcome to the family” message if they just started dating last week.
- Keep it “We” (Usually): Sending a message from both parents (using “We”) feels inclusive and less intense than a long private message from just one parent.
- The “Social Media” Rule: If you post on her Facebook or Instagram wall, keep it short and public-friendly. Save the sentimental stuff for the card.

What to Write in a Birthday Card?
If you are confused and don’t know what to write in a birthday card to your son’s girlfriend, then here are some practical tips:
1. Keep it warm but appropriate: You want to sound genuinely happy for her special day, as if you are writing birthday wishes for your friends.
2. Acknowledge what she brings to your son’s life: A simple mention like “we love seeing how you take care of [son’s name]” or “it is wonderful to see you both together” shows you notice and appreciate their relationship together.
3. Keep it short and sweet: There is nothing wrong with a brief, warm message when the relationship is newer.
4. End with genuine warmth: Close it with something like “we are glad you are a part of our family” or “wishing you an amazing year ahead” that feels genuine and shows how you actually feel her presence in the family.
