For the grinding stick, you can eat it when the baby starts to grow teeth. There is no clear rule that you can only eat for a few months. Because when the baby has teeth, his mouth will secrete a lot of saliva and he likes to bite. And for the baby, biting hard things can exercise his occlusal ability and contribute to the toughness of the gums.
However, some people say that a five-month-old baby will have indigestion if he doesn't add complementary food. At this time, the choice of grinding a biscuit is a knowledge, so mothers must choose a biscuit that is more suitable for their baby, and choose a harder one, otherwise the baby will choke to death if he doesn't grind his teeth. There will be some safety hazards to the baby, so mothers must be careful.
In fact, when the baby feels uncomfortable when teething, in addition to using a grinding stick, the mother can also relieve the baby's discomfort by touching and kissing, which can also increase the affection between the mother and the baby.
