OK, argue back with me people - and tell me IABU!! 
I have recently taken up a full time SAHM positionWWIth 2 DC (2 and 11 months).
Before this i was in a full time job, very good salary, yada, yada, but we've recently immigrated (to my home country) so gave that up. Now, the full time Mum gig I can get in board with, but the housewifery bit... eeehh...
But what can you do? Surely if you're the one at home full time, and bringing in no income to the house, then swiping an iron over a few shirts is part and parcel?
I often see threads where people say they won't iron their DH's shirts but it seems a bit churlish to me to pick the DH's stuff out of the ironing pile and leave it for him.
My DH would never expect, let alone ask me to do his ironing, but I dunno, if I was in his position I honestly think I'd be privately thinking, 'you really can't do it...?'
For the record, I'm not some Stepford wife; I'm a long-time feminist trying to get my head around my new role, and yes, I do realise that you can do or not do whatever you want, housework-wise in the privacy of your own home
but it would be good to hear from any other SAHMs if they have an particular tasks that they flat out refuse to do and your rationale.
