Paediatricians generally do not approve the use of bottle for feeding because of the inherent danger of bacteria festering around the teat area due to improper cleaning. That is why spoon and cup is preferable.

Pediatricians recommends back to sleep as the best sleeping position for infants. That’s laying your infants down on their back. This is to avoid the child dying via Sudden Infant Death Syndrome (SID)

The best sleep position during pregnancy is “SOS” (sleep on side). Even better is to sleep on your left side. Sleeping on your left side will increase the amount of blood and nutrients that reach the placenta and your baby. Keep your legs and knees bent, and put a pillow between your legs.

It is not good. We normally recommend BACK TO SLEEP as the best sleeping position for infants. That is laying your infants down on their back.

There's no justification.... If the baby is falling on the floor, he or she can fall on the bed as well. I'm thinking your baby is not yet able to sit WITHOUT SUPPORT!!

Side sleeping is d best.tummy facing down is dangerous.
