ROCKS!
She always has DS1 on a wed. Still does, even though I'm on mat leave with DS2. I've been ill with a nightmare sore throat and had been to docs yesterday. MIL battled through snow to get here to take DS2 out for lunch. She got stuck in all that awful compacted snow at the side of the road and basically dug the car out (refusing to let me help or push) so she could take me to the drs. Took me to get my antibiotics and STILL took DS1 out for lunch to give me a break.
I know some MIL's can be awful, but think there are still a load of very good ones out there. Mine is an example. Just wanted to share a positive MIL story and give one of the good ones a mention.
