i didn't feel that way about the t-shirt - i don't think it's the fact that she's milk stained and snot stained and knackered and missing her job/ whatever that's bothering her - it's that her partner isn't. it's the equality bit that's missing.
i'm really glad that apparently all of the young parents are doing things equally in rl, noodle. i don't see it by reading mn though. i still see loads of very young mothers on here who have ended up doing all of the childcare and housework, and sleeping in the spare room so that they don't wake the important worker in the house who needs to earn their keep. and then they over-compensate by doubting the competence of a man to look after their baby/ toddler alone.
i don't care who works - man, woman, both, neither. but i strongly believe that if there is a new mother who is staggering around alone in the night or in the day, feeling that she is doing it all alone, then she isn't getting enough support. and i'm not necessarily talking about from a partner (although if she has a husband/ partner and has been a fawcett t-shirt wearing type that would be a good place to start), but from extended family/ friends/ wherever.
all of this 'oh, it's because she's an older mother and used to working, doesn't know she's born, privileged, what did she expect' stuff is really very very sad.
she's a new mum who is struggling. have a bit of compassion.
gwtmh - i used to wait until dh came home from work, then go out for a jog or walk on my own for 40 minutes. just to get out of the house alone and clear my head. that way there is no 'waiting for him to offer', it's just 'there you go - back soon' and out. of a weekend, we would both put our trackies on and take the baby into the woods, and take turns into jogging off for a few minutes and then coming back to push/ carry. as soon as the baby would take a bottle of ebm, he'd do the late shift. and once i'd fed the baby in the night, i'd give him an elbow in the kidneys to go and change/ settle. share the misery as well as the joy.
it's just a case of removing the choice aspect - if i had the choice to go and deal with a screaming baby or drink my tea, i'd like to drink my tea. but it's a parent's job. a parent's job, not a mother's job. dh needs to see childcare as a parent's job. it's easier if you aren't there, then it removes the choice bit.
they do get the hang of equal parenting very quickly... honest. 
and apparently, much more easily if you are young like noodle's rl experience...
