My wife has been breastfeeding our baby boy since birth. And milk demand has naturally increased over time as baby grows. How can she increase her milk supply or should we go for a mixture of milk powder feeding and breast milk feeding? Any advice or recommendation?

How old is your baby? Preferably for the first 3 months, go for exclusive breastfeeding. From then on, you can supplement with formula milk. The tenure of breastfeeding differs for each mom. I know a friend of mine who fed her lo for almost 2 years. My lo is almost 11 months old and I recently introduced formula to complement gradually reducing volume. There are various factors pertaining to milk production - your hereditary genes, your diet and your overall health.
