so I'm posting here! 
DH does his share of the actual work at home/for the DC - mostly. But from the day we moved in together the endless thinking and planning and organising and rearranging and compromising that is all left to me has been a bone of contention which obviously just got worse with kids etc. Culminating last year (after a whole lot of other stuff) in the mother of all arguments over the vacuuming of all things. Since then he really has been trying and I've also been making a big effort to "see" the many things he does that I do NOT have to think about because I am conscious that compared to most, he's amazing.
For various reasons, I have had to concede that I am never going to sort the kids' dental appointments. I asked DH therefore to take it on. Which he has done. But now I am definitely being unreasonable because I am laughing hysterically inside because he keeps having to reschedule the appointments because he's never actually had to plan anything for the kids so keeps booking them in on days that they already have something, or that they can't make it up to the dentist in time or something. I know I shouldn't be laughing but in light of the fact that we've just gone through 7 weeks holiday where DH looked after the DC a lot but didn't so much as organise a single activity, play date etc nor did he even ONCE consider that maybe he needed to reschedule his work arrangements.... I can't help myself. I have so far resisted say, "welcome to my world" as he's tearing his hair out!
[Also, I should mention that I am the main breadwinner and work 40+ hours a week. DH works part time.]
