Co-sleeping

Explanation:

Sleeping with a baby is the most amazing and innocent experience. It's very enthusiastic for parents to cuddle their babies all night. It a sweeter experience.

Co-sleeping is just like to sleep with your baby in proximity or closeness. It happened sometime on the same surface and sometimes it occurs at different spaces.

Sometimes people confused with room sharing and surface sharing as the American Pediatrician mentioned. Some of the researchers say that it is not a proper word co-sleeping. Instead of Co-sleeping people can use word bed sharing or room sharing.  

Thus here Mayan is using Co-sleeping with her newborn baby.
