We have a strange house with 2 en suites and no family bathroom. We have an en suite and the children use the other one , unless we have guests and then they use ours. If we had an au pair we could give her an en suite but would like her to use that bathroom when she is on duty bathing the DC. We of course would bath them in our bathroom if she was off duty.
Would this be unreasonable or would she expect to have the bathroom all to herself? The children have a second loo so only use the bathroom to bath in.
