Babies who do not roll over at seven months are considered abnormal and should be seen at the hospital for treatment. If it is developmental delay, you should go to the child health department of the hospital as soon as possible for consultation and evaluation.
Most newborns learn to roll over around 3-6 months of age. If your baby can’t roll over, can’t reach out and grasp objects, and can’t interact with parents, consider that there is a developmental delay, and you should take your baby to the hospital’s Child Health Unit for a checkup in a timely manner. Parents should also add vitamin D to the baby, under the guidance of the doctor to help the baby training crawling, turn over.
Babies who can’t roll over at seven months also need to be evaluated for diseases such as Trisomy 21 and West syndrome.
