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.
