to be really annoyed that despite telling DH four times to put the carseats back in my car

[BumWiper]

That he is gone to work with them still in his car.And he is on an overnight trip so I cant bring DC to a birthday party tomorrow.Is it only my DH that seems to suffer from ''whoops'' disease?

That's what she's dodging coffee for...

Have you let him know yet?

YANBU. Very annoying!

Well I am great believer that if people are relying on you, as the the OP was on her DH, then you should be reliable!

Strictly speaking, it wasn't the OP who needed the seats, it was her LOs. I think this is where the issue lies. If I need something I will get it. If DD needs something, it is not just my responsibility. Even my, very domestically good, DH, slides into this. DD needs to have her teeth brushed, I want it to be DH's job because feeding, clothing, getting to sleep are all mine. He wants to be reminded. WHY? He doesn't remind me to BF. So, I have to grit my teeth and let him forget sometimes (and clean them in secret on those days ). Not remind him, and have this slowly become my job too. I should add that DH does most of the housework without being nagged reminded.
