I take part in a team sport (not going to say what as it's rather niche and therefore outing).
Every year my club runs a competition and I am one of a core of six members who always helps set up and does the donkey work across the whole weekend (emptying bins, picking up litter, ensuring toilets are clean, fetching and carrying etc)
This year I asked to do specific tasks that I know are less strenuous as I will have 12-week-old DS with me and because I had an emergency section which hasn't healed brilliantly (really hoping I would be encouraged to take a back seat this year).
The woman who runs the club has pointed out all that I am expected to do in addition to competing myself (which would be fine in a normal year) and is pushing me to leave DS with DH for the entire weekend. I pointed out I am BF and the response was "can't you express some" - erm, not enough for two days, no.
She now wants me to bring DH to look after DS. He doesn't normally come to any competition with me.
She was difficult in my pregnancy too - resisting a minor alteration to my technique which allowed me to compete safely until I put my foot down - and has a history of "humorous" digs at me, which I generally ignore but have led to DH trying to persuade me to move teams in the past.
WIBU to tell her to fuck off, I'm not leaving DS nor am I running ragged this year?
