My 22 month old is almost strictly breastfed. He is in the normal weight range and gaining weight very regularly should I be concerned?

Transition. A variety of vitamins, minerals and iron is suggested in addition to milk. Eventually he will transition to cow's milk and wean. A healthy diet should include a balanced diet, meals and snacks at this age.
??Concern?? There are many aboriginal cultures that strictly breast feed up to 2y before graduating the infant to the tribal foods. These cultures seem to thrive so we know it can be done. The problem comes with the lack of interest adding new foods as expected with older kids. Bm is superior up to a yr/but afterward the nurturing is the prime benefit. If kid will let that go it is ok to move along.
