I have my MIL staying this weekend and although we get along ok she does wind me up by constandly undermining me with my 2 DC's, however I let so much go as she only sees them 4 times a year due to distance.
Today I asked if she would be ok watching DC's while I popped to the shops to get bits for dinner and other necessaties, which was fine with her as she likes to spend time with them, I explained that my youngest may fall asleep and thats fine but my eldest (2yrs) doesn't nap otherwise he will be up half the night wide awake (tried and tested).
Well I got back after being out only an hour to find BOTH DC's asleep, I asked how long they have been asleep for and got told about 30mins, so I have woken my eldest up and cue a miserable, sleepy child who WILL be like this now all day until he gets a second wind before bedtime.
I did say to MIL "thanks alot now he will be up all night" which she is convinced I am wrong.
My husband is working up the pub tonight on the door and I am very tempted to leave MIL with DC's when DC1 will be wide awake and stroppy because she broke his routine and I am thinking maybe it will teach her to actually listen to what I ask in future AIBU?
