Mother in law

And so it begins ! My mother in law came to visit her grand daughter for the first time since her birth and she is two weeks old and already starting in on my husband and I about how she didn't do certain things certain ways.. I'm so hormonal I wanted to cry but I held it back but Ughhhh... Why does everyone have anything to say about how others raise their children.. It really chaps my ass ! Anyone else have in law probs??
