1. Pay attention to the baby's feeding style. Bad feeding methods, such as feeding the bottle too high, will lead to the baby's chin sucking forward, leading to anti-abortion!
2. Keep your baby's good oral hygiene and start brushing your teeth. "Mom should help the baby."
3. Go to a regular stomatological hospital or clinic for regular check-up, which is generally a reasonable suggestion once every six months to once a year.
