Is it normal & psychologically healthy for children to sleep in the same bed with a parent?

The AAP, in your: Hometown, has a healthy child app that addresses sleep issues. In many cultures, the "family bed" is a necessity. Infants who learn to fall asleep in their own beds by 1-4 months consolidate sleep & night-wake less. Co-sleeping can impede a child's development of independent self-calming skills, if it's not a cultural norm. Family therapy would help everyone get to sleep in his/her own bed.
