I think many of the MIL threads are about pretty thoughtless (to say the least) partners.
My MIL is utterly over the moon I'm pregnant it's her first grandchild. She asked DP if she could be there at the birth, I wasn't there when DP told her I was pregnant.
DP immiedately told her no, she wasn't to be at the actual birth but she was welcome to the hospital to be amongst the first to see/hold baby and probably will be the first person after DP and midwife.
I reiterated this invitation when she called me later to congratulate me and tell me how thrilled she was at the news.
MIL also offered to buy baby stuff I aksed her to hold fire for the time being (I've had a lot of losses), she complately respected my request, and I thanked her profusely and told when its nearer the due date her offer would be really welcome.
The whole scenario would have turned into a MN thread had DP agreed to MIL being in the birthing room as I would feel uncofmrtable being semi naked in front of MIL and I know I wouldnt be able to concentrate on giving birth.
MIL is also the kind of person who would not expect me to make her five course meals while she visits after the birth, she'd expect her son to be taking care of me.
I love MIL, and we are planning on moving to a larger house so she has a comfortable room if she chooses to stay for with us for periods of time.
But the point is MIL is kind and thoughtful and DP takes my needs into consideration.
EXMIL was completely the opposite and I could write threads about her here on MN.
