Reastie,sorry you are ill and pil'd out too. Im sorry i never answered you by pm i just dont seem to find the time but it goes without saying im in your corner,i so know what you mean about plans to be nice and then they go and piss you off so you dont. This is my theory after musch musing. The in laws are the only people in life who we dont choose to spend time with,rather they are thrust onto us and are involved in very personal aspects of our lives too.
So they maybe very unlike us and have different views and mannerisms and attitudes.
When babies arrive we are expected to be even more involved and unless you happen to be very similar the clashes will happen.
I went clubbing with my dil on Friday cos we are quite similar iyswim?
I wish i had anawers,i feel so sorry for dh and really want to make things better but it never gets easier and i think someof it is my intolerence.
We have just been for a meal with them before they went home.They actually paid for it too 
D woke up just as we had our meals (of course) and i started to feed her,they finished their food well before dh but didnt offer to have her.I had to sit and watch my food go cold until dh took her. (he had offered before btw)
After the meal we just sat there for about an hr,not eating just sat there. Dh was nodding off. D did a pooh and fil looked horrified and was turning his nose up,he also does this when milk comes out of Dillys nose due to her cleft. 
I dont know how to deal with it,I often think id rather be on my own than have to deal with it all for years.The only thing is when D is older he can chip off to Essex and take her and me and Els can have some peace.
I think if you are naturally a private person and a bit protective of your dc's then it is hard to have pils popping in,think yourself lucky tho they done have to flipping stay over and eat.
Vile points this visit. Fil sucking his weasly fingers after eating cake.
Fil allowing Delilah to suck his hairy hands!!!!! How do you stop that politley?
