The baby between 4 and 6 months should already be able to turn from one side to the other, and may lie on their belly down. Usually he learns how to turn that way when he is already in control of his head weight and just before he learns to sit alone.
Some babies can do this at 3 or 4 months of age and there is no problem with it developing faster, however, you do not have to force the baby to achieve this movement before 5 months.
It is normal for the baby to learn to turn to one side and have a preference to always turn to this same side, but gradually it will strengthen your muscles and it will be easier to turn the other side as well.
How to stimulate the baby to turn alone
A good strategy to teach the baby to turn is to lay him on his belly and put a toy he is interested in beside him, so he has to move his hands to reach for the toy. If he is not able to turn you can put one of your hands on the thigh or the baby's hip, giving him a little stimulation for him to roll.
These and other techniques to help the development of the baby you can see in the following video with the physiotherapist Marcelle Pinheiro:
From the moment the baby learns to turn, he can not be alone on the bed because he risks falling and bumping his head. In addition it may be safer to always hold the baby during the diaper changes so that it does not fall.
The baby's motor development can be stimulated, but each baby has its own rhythm. The important thing is for the baby to be able to crawl, sit, walk and talk without help, but it does not matter much how many months he reaches these developmental milestones. However, if the baby is almost 1 year old and still not crawling it is possible that he has a developmental delay and needs to do psychomotor sessions with a physiotherapist.
