Read labels is the first and the most important thing! But the best option is to do your own natural baby foods. I started preparing for the lure in advance, bought organic products in the season of their ripening and frozen. When the time comes for introducing solid food for my baby, I used month-by-month food chard, like here https://mommystips.com/food-chart-easy-to-digest-foods/ and prepare completely natural dishes, steamed vegetables, cereals with natural fruits and breast milk etc. So be conscious, think about the health of your baby.
