I have just been offered an interview for an evening post for four evening a week. It would mean leaving home at 4.15 pm, and my husband doesn't return from work until some time between 6.15 and 7.15. My mum has offered to sit with the children for two of the four days (although she has a house overseas, so this wouldn't be feasible all the time. Any suggestions for childcare for the rest of the time?
