When you have a baby, you're not just given booties and stretch and grows.
You find you become a magnet for people offering advice on how best to raise your child.
While most of the time the advice is helpful, sometimes it's not - a midwife (yes a midwife) advised me against giving my baby formula milk - referring to it as "the devil's juice".
You're also told how you should sleep your baby, if you should wake them for feeds, when to start feeding them solids ... the list goes on.
But some things go without saying, as it goes in the category of common sense.
