Over the weekend I almost lost my mind at my MIL but held back because my own mother would kill me if she knew I blew up at my MIL.

I have worked VERY hard at sleep-training/nap-training the LO but noticed that her sleeping is not ideal and I found out why! Every Tuesdays the MIL comes over for a few hours to watch LO while I run errands and I found out that while I'm gone, my MIL rocks LO to sleep and let's her nap in MIL's arms! It's no wonder she gets so fussy when I try to put her down for naps!

In LO's room we have her nap routine printed out and we showed it to MIL weeks ago when we were training LO...But she has chosen to ignore it all. I am infuriated!

I told hubs that MIL is not welcomed to come over to watch LO anymore unless he's home.

What should I do/say?
