I'm having this right now but I feel it has to do with the transition from school schedule to summer schedule. But, that also being the case the kids are with ex all day long so it may be a combo of both things. I notice our S10 being much more withdrawn and despondent in the last two weeks and it may have to do with longer exposure time to exuBPD/NPD wacko, nut job, sociopath, psychopath... .
The drama and craziness has to be draining, im drained when I deal with my ex after 30 min and when we were together I was a complete mess physically, mentally and emotionally.
Between the poor eating habits at moms (lots of sugar)
My ex is a nut when it comes to food, my daughter has a cavity and my ex blames me because I give my daughter juice
Of course BPDm always sends emails saying that she got a sick kiddo from us because she see the pattern of kiddo getting sick with her and so she must project that, but she is delusional so rolleyes

, its funny(not really) how that works
Maybe that's it, or maybe not. You're keeping an eye on things.
At her age, it goes in cycles as they grow, so it might just be a normal nap cycle.
very true, hopefully that's what it is
