There has been a long debate about breastfeeding versus bottle feeding babies and how it will affect their health. The debate continues. A simple study was done to see if breastfeeding influenced the development of ADHD. Three groups were studied. The first group of children had already been diagnosed with ADHD. The second group of children had siblings with ADHD and the third group had no one with ADHD. A questionnaire was given to the mothers of these children to find out how the children had been fed as infants. It was found that children were more likely to develop ADHD if they were not breastfed from 3 to 6 months of age. While this study was simple it does show a possible link between breastfeeding and ADHD. This is just another piece to the puzzle of which method is better for infants.
