YANBU,my ils have 2 dc & my lovely dh was always & still is always treated like crap by them,this has carried onto our ds.
They bend over backwards to accomodate sil & her 2 dds,they have never taken ds anywhere,pushed his pram or taken him to the park,he is now 4.
When dh pointed this out to them they shrugged & said sil needs more help cos her boyf was an undesirable??
DS started school this sept & they havent been to see him in his uniform,we always have to go to theirs.
They live about 5 mins away by foot.
As far as we are concerned they can fuck off,ds is a lovely little boy & is growing up fast,they are missing out on it all,not us.
Sil loves the extra attention she gets.especially when she can drop them both off & go out on the lash,knowing the girls can sleep in their own bedroom at gpps house,all done out in pink,natch.
