So home from a long day in class (passed my big major test and the class, go me!) get home all the kids are happy to have me home and actually spend some time with me. I ask my kids about their day and...... SO left my 10 yr old in charge of his 4 and 5 yr old for an hour while he ran my DD on some errands and while they played outside. Okay so first issue I have is that is way to much responsibility for a 10 yr old, and both his kids got in trouble said the F word (yeah both of them, yes that F word). Then I found out my DD had to get woke up this morning by her brother to put SO's son in time out (yes I allow her to do this to her brother when she babysits him any other punishment has to go through me) but SO's kids? Supposedly my son had tried to wake SO up but he wouldn't wake up. I know my son doesn't do a very good job trying to wake grown ups I think he's afraid he'll get yelled at. So my DD put his son in timeout and when SO got back from errands he punished both his kids (he is fairly strict on them but kinda has to be as it seems they do and say whatever when they aren't here) So I'm just really not comfortable with my son watching his kids or my daughter punishing them she's just used to the responsibility of her normal babysitting jobs and did what she would of normally. Then as SO's kids are getting ready for their BM to get them his daughter says as she hugs me goodbye "I'm not gonna be good for my mom like I am for you" I was shocked I know there are some issues with their BM but still. So I told her "that would be a terrible thing to do to your mom and would really hurt her feelings if you don't listen and misbehave for her. You be a good girl and work really hard in school" I didn't know what to say. It's weird random things like that, that catch me off guard and I have no idea if I'm saying or doing the right thing!
