Apart from sleeping schedule, it is essential to know about safe and comfortable sleeping positions in order to avoid Sudden Infant Death Syndrome (SIDS) which is the sudden unexplained death of a child of less than one year of age which usually occurs at night during sleeping. 

Putting your baby to sleep on his/her back decreases the chance of sudden infant death syndrome (SIDS) An infant who sleeps on his/her stomach gets less oxygen or gets rid of carbon dioxide less because she/he is “rebreathing” the air from a small pocket of bedding pulled up around the nose.

Even when you are sure your baby is lying on her back when going to sleep, it is also crucial to avoid placing the baby on soft surfaces such as pillows, quilts, sheepskins, or bean bags as they might block a baby's airway if she/he puts his/her face in them. 

Besides, Blankets should be covered only up to the chest of the baby with arms exposed, to avoid the shifting of the blanket onto the head and thereby avoiding suffocation. 

Infants should be light-clothed for sleep. Avoid over-clothing and check if the baby is not hot to touch.

Use a pacifier while baby is asleep but if she/he doesn't want it, don't force. 

It is important to feed your baby at least 30-40 minutes prior to putting him/her asleep in order to decrease the chance of unexpected vomiting during sleep.

Please do not panic and take these safety tips into consideration.
