I have to cancel my attendence at the wedding of good friends of mine on extremely short notice. My 13 week old son simply will not take a bottle from anybody else but me for the last week and was fussy about taking one from anybody else for a week or two. The problem is this. I live in NYC and we are going through a 93+ heat wave at the moment (I think sometime like 32 degrees). To get to the wedding with the baby with me would mean a six hour round trip on busses with my 13 week old son. Not possible in this heat. I can't leave him with DH or anybody else because he will scream his head off but flat out refuses to feed with anybody else. If he would just fuss and go hungry, I'd let my husband figure out a way to feed. But I can't, he would become dangerously dehydrated without constant intake during the day.
I have ordered flowers to arrive the wedding morning to the brides room, but really I am friends with the groom. How do I properly say sorry for not attending and assure them that I didn't just blow them off. Approx. 75 per cent of peoplea attending will notice my absense. Please advise.
