LOL Dach @ MILs being trouble makers. In my case more a pain in the butt and a stupid old cow. (oops sorry insulting cows 8-[ )

Anyway, Misty you are definitley not wrong feeling this way. Of course you would favour your own mum over your MIL. She is your mother, she brought you up from a baby and you have that special bond with her and that will never change.

Your MIL should realise this and as Dach has said ask her how she would feel if her daughters prefered thier MIL over her!!

You shouldn't be feeling pressured by anyone little alone your MIL and if you don't want her at the birth or choose to include her in every thing well tuff luck to her!! Its your life your choice how you want to live it, who you want at the birth etc...

Hopefully now your SIL is pg she will leave you alone a bit and concentrate on her own daughter's pregnancy.

Good luck.
