I have a bed and 1 long side of the bed comes in contact with the wall.
A mom and a kid are lying on the bed.
The kid is lying outside and close to the other side of the bed.
The mom is lying inside and close to the wall.
The kid might toss around and roll off the bed.
In this situation, in Vietnamese, we often say "the mom lies inside" and "the kid lies outside".
I am not sure how to say it in English. Here is my attempt: "The mom should lie outside and the little kid inside because the kid often tosses around in his sleep and fall off the bed"
Is my attempt correct?
