Newborns are able to turn over on their own four months after birth, but the degree of autonomy is not the same for each child, and it depends on whether the child was born prematurely or not, and whether the parents usually give the child more training. So if the child still can’t turn over at four months, parents should not be overly worried. If the child is premature or has neonatal hypoxia, most of the children will have delayed brain development, and the child will be relatively backward in large movements. If the child has not turned over in four months, parents can give the child more training in general, preferably in the children’s rehabilitation department of the children’s hospital for rehabilitation training. In general, if a child can turn over on his or her own before June, it is basically a normal phenomenon. If the child’s mental state, milk consumption, growth and weight are basically normal, you can wait until the child is six months old and then analyze the situation on a case-by-case basis.
