The neck collar for baby swimming is generally under one year old, because the neck of the baby under one year old is underdeveloped and cannot fully support the baby's head. At this time, it is easy for a baby to break his neck when swimming in the water, so he will use a collar.
Although a two-month-old baby can swim with a collar, it is risky for a small baby to swim with a collar, and it is easy to hurt the baby if he is not careful. Mainly because the baby's neck is very soft, swimming around the neck may hurt the baby's cervical vertebra, and there is a lot of blood circulation around the neck, which can easily lead to poor bleeding if it is not handled properly.
In fact, many experts believe that under the premise that the safety needs to be verified, the neck-type swimming ring should not be used for the baby as far as possible, and it is not recommended to swim when the baby is too young. It's not too late to learn swimming when the baby grows up slowly, which is also good for the baby's physical development.
