I am going for an interview for an evening post (I posted a thread earlier) and I'll need childcare for DD1 aged 2.6 and DD2 aged 7 months from 4.00 until somewhere between 6.30 and 7.00 for two evenings per week. Do childminders work these sort of hours, and if so, would they provide tea (if so, how much extra would this be), or do I bring something for them with me? Also, how much do childminders/nannies etc cost?
