I have arranged for my baby to be christened on the only day this year when that is likely to be possible. Choice of dates is restricted by limited availability at church and because the godfather
(who is my baby's uncle) lives abroad and covid travel restrictions apply.
I invited my parents to the christening and they declined saying they won't be coming as they are already babysitting my two children the night before and the christening is on my father's birthday. For context, the babysitting the night before had been arranged before the christening and is the first time this year I have asked my parents to babysit, they had seemed to be looking forward to it. My father does not usually do more to mark his birthday than perhaps have a pub dinner with my mum - not even always that. The christening is in the evening and will be over by 7pm, so dinner at 8pm would be very do able. Anyway, disappointing and a bit hurtful but crack on.
I spoke to my mother by video call and she repeated that she and my father would not be coming to the baptism. I confirm that I had received the text message to that effect and said I hoped that they had fun doing whatever it was they had planned. At this point my mother became a snarling animal screeching at me not to be "putting this on them. " I pointed out that I had wished them a good time and nothing more and bought the call to an end.
My sister has since called me to say that my parents are very unhappy about the date I have chosen for the christening and seem to think I should postpone until next year and get a nod from then before setting a date. My farther apparently said that he would not be coming to the church in any event, whenever I have the christening (he went to the christenings of his six preceeding grandchildren). Mum says she is terminally ill and the prognosis is that she will die this year, so if that is all correct then she would not be coming to the christening next year either. I think this is bat shit crazy behaviour and have told my sister I will not be cancelling the christening. She agrees that I shouldn't but wants me to get in touch with my parents and try to calm them and persuade them to come. Tbh I would rather not engage. What would you do?
