Giving your growing baby food early on can be quite dangerous for their fragile little bodies, increasing their chances of obesity, heart disease and diabetes in the long run and at present risking infection, choking and undernutrition. So the World Health Organization (WHO) therefore recommends all mothers to practise exclusive breastfeeding for 6 months, if possible, which means that no other liquids or foods are given in the first 6 months of their baby’s life. And if you really, really want to introduce solids, you should wait at least 17 weeks to do so.
