I work part time and my DH works full time but travels all over the country so usually has a day a week WFH which I use as a work day whilst he looks after DC.
On his WFH days he never has much to do except a couple of phone calls so I don't feel bad using him as a babysitter. However he doesn't even do babysitting properly as DC has said he takes them round to their grandparents and leaves them there! He also uses WFH days to play sport too so it's not hard to make time for his child!
What annoys me though is that he sits watching TV on a morning whilst I get breakfasts, empty dishwasher, make lunch and tidy up. Then as I'm rushing around to get to work he asks why I haven't got DC's clothes out yet! Adding insult this morning he commented to DC "I guess we'll have to get the duster out whilst mummy goes out" as if I'm off on a jolly! I do all the housework and 100% childcare when I'm in.
As per another thread I'm probably just sleep deprived and over sensitive so being bitchy to me will get a bad reaction!
