C.K.
my MIL used to have an anything goes approach, but they're the only family we have here, and she's super sensitive. She either got angry and would cancel that week on me, or would undermine me to my son, by saying "oh mommy and her silly little rules". I was ready to forgo any free time and cash i would ever have over it, till my mom and I talked about it. My mom told me to leave it alone...her house her rules, dont worry she'll get sick of it soon. And my mom was right, this is my kids' grandparents no matter what. Grandmas house was always more fun, bcause of the lack of rules, and kids need to be able to adapt to different places different rules. As a child I'd sleepat grandmas on weekend and get LOADED up with sugar,so by the time my parents picked me up I was a maniac. Cocoa and chocolate cake for breakfast, after staying up all night to watch dynasty reruns. I was three...not ok. As soon as I stopped harping on her she changed her tune. I continued to reinforce the house rules at home, and while it was difficult at first, my son got the message about grandmas house vs mommy's. My MIL also got the message when her anything goes house backfired and he now slaps her across the face every time he sees her(she thought it was funny once), and has broken many antique items she refused to put away. Not ok in my house mind you, but made possible and even a joke in hers...untill now. She now asks how I handle situations "so we can be consistant".
