Over the past two days, FIL and stepMIL have probably provided about 10 hours worth of baby sitting so that DH and I could go to a show and then get our house ready for company, do the holiday cooking, etc.
If they are up at 4 am and DD was awake, I really wouldn't care if they got her up. More sleep for me! I'm sure DD would make up her sleep the next day. One night won't kill a schedule.
I got up five times with DD last night. I WISH someone had taken initiative to just give her a bottle so that I could sleep!
I think I run a pretty tight ship in my home (my ILs always ask my permission to the point that I *almost* feel bad)...but I think a little less ridigity wouldn't hurt anybody
