My mum has invited our whole family (wives, husbands, children etc) to a house in Kent for three nights, to celebrate her 70th birthday.
The dates are 13th, 14th and 15th September. However I am due with our second on the 3rd September and am having a c-section which will take place on 27th August. This means I will have a 2 week old baby and be recovering from a c-section and so have spoken to my Mum and said that we won't be able to join but that we can celebrate back home on her actual birthday (17th). I am now feeling very guilty about this. But am being told that it's okay to have said no. So please tell me, AIBU??
