Hi,
Womens' milk has been thoroughly studied - and it's amazingly uniform across all economic situations and types of diets.
You can breastfeed beautifully on a tim tam and a can of coke - but you will feel like hell yourself. And being a mum, you want to feel as good as you can. It's important to your own health and well-being.
I often suggest that, rather than worrying about babies getting into a routine, they put themselves in a routinve - write yourself a little chart to put on the fridge and tick off when you have eaten something healthy.
