Researchers found that babies who breast-fed during vaccinations cried for 38 seconds less on average and had lower pain scores compared with those who didn't breast-feed. The findings in the Cochrane Database of Systematic Reviews, based on a review of 10 studies involving 1,066 babies ages 1 month to 12 months, also showed that breast-feeding more effectively reduced vaccination pain than maternal cuddling or massage, pain creams, injection site sprays, or sugar water.
