Here's a rather unexpected benefit of breastfeeding: breastfeeding your baby during early infancy (the researchers defined that as up to age three months) may reduce the likelihood that your child will have problems with bedwetting later on. A study reported in the June edition of the medical journal Pediatrics found that bedwetting was less common in children ages 5 to 13 who were breastfed than in children the same age who were formula-fed.
