My sincerest condolences for all of you having issues with the MILs/FILs - that's horrible, and honestly, it's no way to be treated during a pregnancy - or anytime for that matter. Hopefully all of this will be resolved for everyone in the very near future....too bad there wasn't a "what to expect from your MIL when your expecting" book - the stories would be endless, I'm sure.
I agree that it seems hard to be thankful for a 'half-hearted' apology - but in some senses, it's better to recieve something than nothing at all.
My brother went through a similar situation with our parents when he was expecting his first. He hadn't spoken to the parents in years, and thought he would try to bury the hachet (so to speak) and let them share in their joy - well, share went to far and the parents put an announcement in the local paper, when my SIL was only 8 weeks in. Needless to say, they were pissed, and in my opinion, rightfully so.
The point I would like to make (in the words of my brother) that now that we are parents, sometimes *and as hard as it is* we have to put aside our feelings and do what is best for the young. The fact that we may be mad now will affect us, then affect the young - if we let this stew until after the kids are born, then we may lose a chance altogether for the bond that grandparents and our kids have.
As hard as it may be, I guess we have to start being the parents now - even if it is to our parents / parents-in laws.
And sorry if that sounded too preachy
