Whether the baby sleeps on the side or lying down is not good or bad, the two sleep positions have their own advantages and disadvantages, alternating replacement is better. If the baby often has the phenomenon of milk overflow, you can take the side of the sleeping position, this will be conducive to the baby in time to spit out the mouth, to prevent choking or accidental inhalation, and is not prone to choking phenomenon. But there are also disadvantages, before the age of two, the baby’s skull is not completely closed, if always side to side sleep, easy to lead to the face is not correct, this age of the baby needs a few hours to adjust the sleeping position. Lying flat to sleep on the baby’s body pressure is relatively small, and you can see the baby’s face, communication and exchange with the baby, limbs can also be free to move. The disadvantage is that lying flat is easy to choke, if there is snoring and tongue falling back may cause breathing difficulties, but also cause the baby flat head, sleep is not solid. The baby’s sleeping position needs to be adjusted according to the actual situation and alternately replaced, thus avoiding serious situations.
