Many infants and toddlers have breath holding spells when they cry. Some babies with a specific heart defect TOF also can turn blue when they cry. It would be best to bring your concern to the pediatrician, who would be checking his heart anyway during routine check-ups. If there was something wrong with his heart, it would show on exam with other findings than just breath holding.

such episodes are not unusual, but it is important to exclude any other reasons for the episodes. Once pediatrician has checked the baby and if everything is ok, it is comforting.
