Just to be clear: this is not a big problem, I am just curious about a funny behaviour :)
My daughter is 13 months old now and I sometimes sleep next to her at night. This can happen when for example we spend the night in a hotel were no cradles are available, so we book an extra bed and we put them all together. This way, she has a full grown-up person bed for her.
Then, during the night she will sleep tight but somehow moving back and forth, rolling, twisting, etc. Every time I check she will be in a completely new position, so I may have her foot next to my head but half an hour later she will be at the bottom of the bed.
I understand this like as: if I had a bed on this proportion (4x4 meters with no boundaries) I would move this much, because involuntary movement during the night would not find limits and my body would just go on doing them. But still, I am not sure if this is right.
So: is this absolutely random movement normal during the night? I assume there is no problem on it, but just in case: is it good for her?
