about 3 years ago when I was 15 my cousins came to Australia with a 8 month old and a 3 year old, they would work from morning till night so as I would wake up i spent 12 hours a day caring and babysitting them fro changing nappies, making sure the night before there was milk kept and made ready for the 8 month old, bathe them, sleep with them if they took naps to ensure their safety.
