New grandparents

Our daughter phoned us last night to inform us that she is expecting, early days yet so not going public, why am I posting you may enquire, obviously my husband and I are pleased but she has never really been the motherly type, she likes children but always said she liked them in small doses. She has been married for 7 years and with her husband for 10. They always seemed content and has never mentioned wanting a child but apparently have been trying since the wedding, she is late 30s so an older mum. I had her in my 20s and never felt the need for a second child. We speak more or less daily. She doesn't live locally and am wondering how to support her now and after the birth.
