I have'nt taken action yet but am on the verge.
Basically BIL &SIL live near PIL (I have posted about this before) and PIL mind my DN's 3 days a week, including Saturday so BIL and SIL can both work. And on Sunday when they are off SIL sends BIL over with the DN's so she can do housework. Her parents have the DC's Mon, Tues & Weds - not that it makes any difference to what I am writing about.
PIL have voiced to me and DH in the last couple of weeks, and for the first time, that they are starting to tire from looking after 2 under 5's so much. Which we could see coming about a year ago, but said nothing.
When SIL phoned over holidays and moaned about PIL not helping with cooking and washing up over Christmas along with loads of other little things. Including MILs minor health concerns she has.
DH and I (as have said before) feel my PIL are being put upon, but because SIL admitted to me threatening MIL before with not seeing the DC's if she makes waves I dont think they will say anything.
But it has got to the point where I feel I want my PIL to know what SIL is saying about them when they are doing so much for her and BIL.
The last time I spoke to SIL I ended the call saying I had to go because I was so cross at what she had said.
Should DH and I say anything?
