Probiotics have come to the forefront in new-born formulae, supplements, and food products. You might be wondering what probiotics are, if they're safe for babies, and if they can help your child. Probiotics are known to be beneficial bacteria. These bacteria are considered to be beneficial to your gastrointestinal (GI) system and aid in the treatment of a variety of ailments. Probiotics appear to be safe and well tolerated in normal, healthy new-borns and children, according to research. Premature infants, very low birth weight babies, and HIV-infected adolescents and adults have shown good tolerance. Late in pregnancy, probiotics are also safe to utilise. Because infants are born with a sterile gastrointestinal system, they may benefit from probiotics. Infants accumulate bacteria that helps them establish a barrier in their GI tract, strengthen their immune system, and avoid infections over time.
