I loved my mum and had a great relationship with her but never had her at either of my DDs births. She never expected to be included and was always the first person I called when the bub had been born.
Since she has died and I have spilt from my 1st husband I kind of wished she had been there for DD1's birth cause then there would have been someone besides me who remembered the birth but its no big deal.
I think its rude of her to expect to be there, I certainly don't expect my DDs to have me at their births.
