Thanks, lorrycat, for your kind words, although don't worry, I do realise some of the flack on this thread was tongue in cheek and ironic.
It's nice of you to say 'good on you' because I take DD to toddler group, but I'm not sure it's needed. If I'm the primary caregiver, that's my job, surely?
CrackFox said it's not a scintillating offer, going to 'the hell that is Mother and Toddler group' (is that what it's called round your way? not Parent and Toddler?).
I'd say firstly, our Toddler group is not hell at all.
And secondly, the thing my DW regrets about working full time is NOT being able to participate in DD's normal life. Going to the Toddler group is part of that, which is why I strongly invited her.
Anyway, she came, and made it clear she was still irritated with me. Thus making me look like a prat to the mothers who know me, who could tell something was up.
