I think the cost may be prohibitive for us but can I just check what a nanny (live out) would expect to earn (gross) on the outskirts of London for 2.5 days (8-615 for 2 days and 8-12 for 1 day). One DS 1 yr old and no housework required, just preparing his food.
I thought it was going to be doable financially but my search is telling me not so I thought I'd ask good ol' mumsnet before I give up hope.
