I used to like them. I had a lot of respect for them - they raised two fabulous boys, dh and his lovely brother who are kind, generous, loving men. They are a close family and live near us.
However, since having ds2, they have completely changed. He has been very ill with reflux and was hospitalised a few times. So we needed their help and support more than ever. I have PND too.
basically, anytime we are with them, they give constant unwanted 'advice' about how we should be dealing with him. First it was that I should be givng him formula, not bfing him as they believed this would help (!?) and they just wouldn't let it go. FInally they have stopped but now they go on non stop about 'solids' and how they are the solution to everything - I do think they might help WHEN HE IS 6 MTHS, but not before.
But worse than this is that they say things like 'we will come up and take ds1 out for the afternoon' to take a bit of pressure off me. Then phone and cancel at the last minute because they have to meet a friend for coffee. 
Fil is totally useless and goes in the huff when we do not do what he wants, like staying over t family dos - which would be awful with ds2 not sleeping.
We are exhausted and need sympathy from them. Instead we get constant criticism.
