Totally agree with "having time off", if you can.

Andrew looks after Olivia for me for a half day on either saturdays or sunday most weekends and it keeps me sane........this morning I was out an about by myself at 8.45am, had a manicure, a pedicure, went for a bit of a trawl round the markets, popped round to GF's for a coffee...........it is only for a few hours, but makes me feel like a new woman by the time I get home!
