Summer is the season when babies have frequent gastrointestinal problems. Supplementing probiotics in time at this time is helpful to adjust the balance of gastrointestinal flora and relieve or prevent gastrointestinal discomfort symptoms. I choose French synbiotics probiotics for my baby, twice a day, one bag at a time, and put them in the milk powder that my baby drinks in the morning and evening. Persisting in drinking can also improve the self-protection ability, so that the baby is less sick and naturally grows well.
