I need help telling my mother

I posted the other day and did not get much of a response. I'm having my first baby in August and my family lives 1500 miles away from me. My question is how do I go about telling my mother that she's dying to have a grandbaby and I wanted to be as personal as possible. If you have any ideas I would gladly appreciate you sharing them with me so I can tell her sooner rather than later. Thank you very much everyone and I can't wait to hear from you guys.
