Well I think a lot of kids start babysitting at 12 or 13. As long as S15 is comfortable and D9 is fine with it, I don't see a problem. S15 should have the landlord's phone number, your number and be fine addressing minor issues but knows what to do in case of an emergency.
Time for your H to give you some credit.

Right, plus summer camps will give S15 a break from babysitting, and I'm hoping I can hire one of my theatre friends (she's about 17) and a homeschooler, and really nice, already friends with D9 and she'd really just have to babysit D9. And just be there in case of emergency or whatever. I don't think I could hire her all my hours, but maybe at least a day or 2, so S15 would only have to babysit a day or 2 also.
H emailed me today be sure to have D9 wearing her glasses and something about their phone not being charged. I told him I charged the phone they've been using at my house last night and will charge their phone they use at his house when I have access to it (its with them tonight at Hs). D9 took off her glass again today and I got them and asked her to put on again. She was in the bathroom, and then I was cleaning and helping S15 with his history assignment (for virtual school). I couldn't find the glasses when we had to leave. I just found them when I got home on the computer desk on the top of it, must have put them down when helping S15. I emailed H sorry for not having her glasses on. He made a big thing she doesn't have her glasses when I dropped them off. I just emailed him sorry, and what happened and that I will try not to do so much at once, and have encouraged D9 again today to try to keep them on until she goes to bed. Then I said but she's 9, and imagine if he'd had them at 9.
Honestly, I hate the way I get stressed out before dropping them off and picking them up, like he's my dad, well a dad, my dad was actually a nice, sweet guy. Need to work on that. I feel so happy when it's over with each time! Karen
You know he should buy her a second pair. Again he is out to make you look like a bad person/mother. No one in their right mind would think that only your crazy H. Gee, when is this divorce going to be over??? You are coming up on a year!

After I sent the sorry and explanation about the glasses he emailed back I send home her glasses so I simply ask that you do the same. And another email saying he's charging their phone that they use at his apt. (gee why didn't he do that in the first place instead of complaining to me about it then?). He sure spends a lot of time emailing me for someone that he wants out of his life. I'm in proper DB mode again and just ignoring them and no reply. Um, he's supposed to be spending time with them tonight and he emails me! Karen
He is a mess, plain and simple. Maybe they really did break up. Do the kids even mention seeing her or Dad texting all the time like he used to? Not suggesting that they spy, just asking if they mention it.

Well, D9 just told me yesterday or today they went to a pool party about a month ago, the kids, and D9 told me OW was there and teamed up with H to play bocce against D9 and S15. How creepy to go to a party with families and stuff and they're both married and with my kids??? I do think they're prob. perfect for each other. Karen
They don't think, they don't care oh why even bother trying to figure them out??!! Someone has to keep their head on straight and in this situation, it is you my dear.
When stuff like that happens with my kids I try to talk it out with them. You know my ex does dumb stuff like that all the time, trying to force them all to be together. What an idiot!! We just have to rise above it somehow. I hope you are making a wonderful day.

I am. Just got back from work. I'm thinking I'm going to go and get one of those doggy door things for my dog, so he can get in and out tomorrow.
H called today & left a vm for me. Wanted the kids an extra night tonight b/c he has a long race on Saturday. I agreed, and will pick them up tomorrow after work. I hope he's actually taking off some of the time and not just leaving them home alone in the apt. all day. I'm still applying to weekend jobs, there was one at the local hospital yesterday, and a nanny job (was hoping I could take D9 with me and she could play with the kids which she would love? H is going to use my p/t job as a problem, although he leaves them in the apt. when he's alone. But somehow it's different (worse) when I do it for a half day.
H was super friendly today, I guess b/c he wanted something from me. Karen
H is stressing me out again. He normally has the kids Tuesday night and asked today for Wed. night also instead of Friday night b/c of his race Saturday. I agreed to that. Then he emails me that he also wants Sunday am to Tuesday afternoon instead of Tuesday night (usually has them for about 24 hours). Am I crazy being suspicious this is occurring right before our mediation next month? You know a year ago he didn't have them for any overnights, then 6 months ago he starts having one a week and then a couple months ago to 2 nights. Now I'm wondering if he wants to go to 3. I really don't have a problem, except I'm concerned he's motivated by $$$ rather than wanting to be with the kids. He goes running and to work and leaves the kids in the apt. and they're not supposed to go out.
I hope you have documented as much of this as possible. He is such a slime I wouldn't put it past him. but also document again as much as possible if he is actually there with them or at work etc. Only say yes if you feel okay about it not if you feel manipulated.
