Please don't worry about your "rant," beautybumble. That's one of the things this forum is for. Better for you to vent here than at your AC and CIL, LOL!
I must admit, I'm a little confused though. You titled this post, "Looking after grandchildren getting too much." So I thought you were going to say that it's getting too hard for you to babysit or that it's expected too often or for too long hours, etc. But while it seems you AC take your help w/ kids for granted, your post seems to focus more on your need for more time w/ and appreciation from your AC. Which is the real issue?
Or is it a combination, as some posters have suggested. Would watching the grands seem easier if their parents showed more appreciation and interest in you as a whole person (not just a childminder)? Or would you need less support from them if you weren't watching the GC so often?
If it's any comfort, I think your AC's behavior towards you is very common and not intended to be hurtful, etc. Most young parents, IMO, are focused on themselves, their lives, the needs of their own families. I doubt they often stop to think of the fact that we, too, have lives - lives ourside of theirs, LOL!
But that's why I agree w/ others that the best solution to this problem would be to get involved in some separate activities or take up a hobby that needs your full attention for set times of the day/week. The let them know you're not available on this and that day or at these times b/c you've joined a new group, etc. This will get you out among other people, cut down on the amount of childminding you're called upon to do, and remind your AC that you are an individual w/ your own interests, etc.
Should you tell them how you've been feeling or that you'd like to be invited to tea, etc? If their lives are as busy as most young families seem to be these days, they may just see it as one more pressure (sorry to say). Or they might say, in effect, "Oh, of course, Mum, we didn't realize you'd want that, but of course." You can make a better guess than I as to which way they would react. But if in doubt, don't. Just beef up your own activites and start setting some boundaries.
Please let us know what you decide to do and how it works out!
Another week, another Tory MP sex scandal!
