Fully prepared to be told IABU but need to know. Mil has taken ds1 (2yo) while I get some time to rest etc with ds2 (2wo). I didn't ask she just arrives to take him but that's for a different thread! So just saw on fb that sil has actually taken him out for the day without saying anything to me. AIBU to want to know where and who he's with or am I being controlling?
