I don't mess with or worry about vitamins or supplements. I don't obsess over him not eating as many vegetables as I would like, all mainly because I know he is still getting a large amount of the vitamins and nutrients he needs from my milk. In addition to all of the aforementioned vitamins and minerals breastmilk provides, it also shifts to have a higher fat content when your toddler is between the ages of one and two, which is really important because a higher (good) fat ratio is important in their growing diet to meet their needs.
While breastfeeding a toddler, you also continue to reap the benefits of decreased risk of illness and shorter illnesses when they do get sick. Breastmilk continues to provide immunity and protection after the age of one. And while we're talking about better health, continuing to breastfeed your child is good for YOU as well! Mothers who breastfed (in some cases, the longer you nursed, the less of a risk you enjoy) have been found to have decreased risk of breast cancer, ovarian cancer, uterine cancer, endometrial cancer, osteoporosis, rheumatoid arthritis, cardiovascular disease, and type 2 diabetes (if you did not have gestational diabetes). So, not only are you helping your child to be healthy, you are helping yourself to be healthier at the same time!
Additionally, there are some studies that suggest cognitive skills, mental skills, and social skills are positively influenced by breastfeeding, in some cases the longer your child nursed, the more benefit they obtained and the higher they scored on certain assessments. With everything I do for my child already, I consider it to be just one more thing I personally do to aid in his health and development.
