Got a quote off a e-newsletter of a rather well-known hotel cum casino here in Singapore. Very apt for parents like myself:-

One of the essential, must-miss experiences of being a parent is sleep deprivation. After having children, any number of nights out on the tiles is nothing compared to the weeks, nay months, nay years of having some scrimmy mite, park him or herself next to you in your bed and dig, kick, snore and scratch their way through the night...and that's just my missus. Try having one of the kids in there and all hell breaks loose.

Have a good weekend!
