I am a mum of three. Going back to work next month. Baby will be 7months and will be going to nursery full time. 2, older children, aged 8 and 4.5 in primary. I am wondering wether I should get a nanny to help from 4-8, mothers helper, or au pair. I anticipate needing help with laundry, tidying girls room, and feeding girls. I can deliver all kids to school and dad collects older 2, I will pick up baby from nursery.
