The richness in the number of postures that the baby adopts throughout the day will be a decisive factor in his motor and sensory (and, indirectly, intellectual) development, so we know It is convenient to leave the baby on the floor, but in what position?.
The two positions that the baby adopts most on the floor are face up and face down. In some research books on normal motor development (such as "Moving in Freedom" by Emmi Pickler) it is argued that we must always leave the child on his back because the other posture generates some limitation of movement and overwhelm (since he has to turn his nose away and the mouth to one side or another to breathe well).
It seems reasonable, but I think that the baby should not be treated strictly, but behave naturally: sometimes turn it upside down and sometimes down. The idea of putting him upside down is very much influenced lately with the recommendations to avoid "sudden death" but this does not have to make us deprive our son of a specific position, since the recommendations are not to put him in this posture while sleeping. If he is awake and we are near there will be no risk.
If you are looking at the ceiling, you will be able to contemplate your hands, touch each other, grab a toy more easily or just see us.
If you look at the ground, you will have to strain to lift your head and the upper part of the trunk, use your hands as a support (not only as a manipulation tool) and strengthen your back and shoulders. All this will also prepare you for crawling, which will be the first form of displacement you can develop.
In conclusion, the combination of postures on the floor will be the best option for the baby to develop in an integral and rich way, so let's look for a place and a moment a day for them to do so.
