I actually had my hill to die on moment in the past couple of weeks, and boy did it feel good! Every year we spend Christmas day running here there and everywhere trying to fit everyone in, then boxing day at SIL's and the 27th everyone comes to ours. This year, I will be 37 weeks pregnant on Christmas day. Thankfully, MIL and FIL are coming early this year (they live abroad) and so we're doing Christmas with them between the 8th and the 16th of December, so that they can then travel back again at the end of January to meet the new arrival.
I kept getting texts from SIL about boxing day, what are we doing, when will we be there, etc. which was driving me nuts! Eventually, I told SIL that while I would love to commit to boxing day, there are no guarantees that baby won't show early, plus my consultant has been talking about admitting me early because of some complications, so I may on bed rest in hospital, so I just cannot make a firm commitment. I then got the whine about needing to know numbers, how can she plan if she doesn't know whether or not we are coming? So I told her if you want a definite answer, it will have to be a no this year. Of course, suddenly the need to plan is no longer a problem, just let her know nearer the time if we can make it.
I think to save the peace and give me a break I'll send DH and the kiddos to SILs and I'll spend the day at Mums, as it's near my hospital, but this year I am not bending to their wishes in order to keep the peace, so SIL will have to just do without me.
