Congratulations on your new grandchild.
Sadly social media is the way of the young.
My only son lives about 5 hours away , in Hertfordshire,and when my grandson, now 5, was due I heard nothing but sent an email that evening to say hope my daughter in-law was well and surely they wouldn't have long to go, only to get a text about half an hour later to be told he had been born that morning!
I was asked not to visit but knowing he was likely to be an only child as they had already said so I could not wait months to be invited so after 2 weeks I booked an overnight hotel in London and took a train to visit, I told them I was doing it and would not stay long. He was wonderful and yes my daughter in law was struggling, it was much more traumatic than she had imagined and he refused to breast feed.
I do not regret it but be warned they still don't let us see him much now
