Depends on the situation.
I find my ILs massively overbearing.
I am very lucky to have their support, due to the type of job they have, plus retirement, I can always count on them to help out, I am extremely grateful for this.
But it is just helping out, I can afford an extra day here and there at nursery etc, but always ask them as they are so keen, and are desperately put out if I don't.
But on the other side, they then seem to relish in the fact that we "need" them and this seems to be to them an open invite to just butt in on all sorts of things that are just not their problem.
It's like a catch 22, I do sort of rely on them, but I give them an inch and they take about 300 miles. If I don't they are incredibly put out and are even more overbearing.
"Oh you put DS into nursery the extra day, we would of had him. Can't believe we missed him." And the like..
Everything they do is incredibly kind, but it's fucking suffocating! Please don't come around to my house and now my lawn. Yes we could probably do with the help, but it wasn't asked for, and now I feel guilty if I don't spend all of my spare time or give up my only time with my son at the weekends because you are so incredibly fucking nice!
Sort out some boundaries; because next thing you know you FIL will have cleared your guttering out and replaced a leaky drain pipe whilst your at work, but then be put out because you refuse to do a 7 hour round trip one Sunday to meet family with only 2 days notice...
