Breastfeeding

Ms Waters, from the left-wing Greens party, fed two-month-old daughter Alia Joy during a vote on Tuesday.

The lower house last year joined the Senate in allowing breastfeeding, but no MPs in either house had done so.

It followed a backlash in 2015 when Kelly O'Dwyer, a government minister, was asked to consider expressing milk to avoid missing parliamentary duties.

"We need more women and parents in Parliament," Ms Waters said on Facebook.

The biggest concern with vegan diets in early childhood is nutritional inadequacy. Parents therefore need to be very well informed otherwise there's a risk of vitamin D, calcium, iron and possibly vitamin B12 deficiency.  

So what are the most important points parents have to remember when feeding their child a plant-based diet?
