DH is the breadwinner but we both work full time, DC in full time childcare as no family support nearby. I do all nursery drop offs/pick ups and the emergency leave when DC are poorly. DH role does require some travel and I totally appreciate I can't expect 50/50 split of parenting duties (for want of a better phrase!), but would like some level of sharing them. AIBU? Should the breadwinner be able to focus solely on work? Keen to learn how others share when one parent is in a much more senior role than the other
