does birth of a grandchild bring out the worst in MIL's?

I dont have a MIL, but I have inlaws who think they are my MIL (males and females) ha ha ha

Here is a classic case of "The change is not with the world the change is within me"

It is us who change, the MILs and others are the same persons !

Actually till we get pregnant/have a baby - we are just girls who have studied, manage a home (mostly independently) and go to work.

During pregnancy and after a baby - there are so many life changing happenings - our hormones, emotions, health aspects and work and responsibilities - all of them change so extensively and in so ways and manners !!

And due to that, our equations with our relatives changes (DH, MIL, parents), we depend on them, we have health issues due to which we are weak, so we become more sensitive, we are worried about many things, we expect somethings, we ask for one advice, they give something else - they have also had children and experiences and we discuss them and we sometimes judge them or get judged - all these equations change!

Everyone thinks that they are doing the right thing and acting concerned - but we perceive it differently because we are wearing a different set of glasses !!!

We speak up for our kids and they take it differently, we wouldnt have stood up for ourselves before (we ignore when we get judged, but we dont ignore when our kids get even some harmless comment) so their perceptions also change - oh DIL never spoke before, she has become very rude now!

All this adds up, we get more defensive, they try to explain more, we try to explain more and though communication is happening at words and actions levels, the communication doesnt happen at the heart level - and all relationships go for a toss
