Marital instability among couples may deeply affect children's sleep pattern, finds new study.
Specifically, researchers found that marital instability when the child was ninth months old was related to child sleep problems at 18 months, including difficulties falling asleep and staying asleep, according to Anne Mannering, an Oregon State University faculty member.

"Parents should be aware that stress in the marriage can potentially impact their child even at a very young age."
Researchers interviewed more than 350 families with adopted infants in order to eliminate the possibility that these shared genes influence the relationship between marital instability and child sleep problems.
"Our findings suggest that the association between marital instability and children's subsequent sleep problems emerges earlier in development than has been demonstrated previously," she said.
The study has been published in the journal Child Development.
