Parents who fight can affect their children's sleep patterns. A study in the journal Child Development found marital problems can lead to sleep problems in very young children.

The authors found that an unstable marriage when the child was just nine months old was linked to sleep problems in the infants when they reached 18 months of age.

Researchers say the findings show that infants can sense their parents' stress, even if they're too young to understand it.
