I have agreed with DP to have DSD for his usual contact weekend next month as he is going to be working. Backstory is he has been out of work for a while (self employed) and this job is a Friday- Tuesday staying away and is worth a lot of money to us that we desperately need.
All was fine until yesterday I received an invite to my nephews christening which is the Sunday of the contact weekend. It is a 3 hour drive away from our house and I would have to take my mum as she does not drive as well as my kids, there would be no room in the car for DSD. I have asked my partners mum but she is unable and DSD mum wont swap the weekends to the week before or after.
We really need the money (currently struggling with mortgage payments and bills) but on the other hand I don't want to miss out on this event and my mother would struggle to attend without the lift from me.
What is the best way to handle this!?
