Erratum

Upon publication of the original article [1], it was noticed that in the discussion section, the sentence “Setting sleep limits contributed to variance in depression scores for mothers and fathers only at follow-up and for mothers, the relationship was negative (more difficulty setting sleep limits associated with lower depression scores)” was incorrectly given as “Setting sleep limits contributed to variance in depression scores for mothers and fathers only at follow-up and for mothers, the relationship was negative (less difficulty setting sleep limits associated with lower depression scores)”. This has now been acknowledged and corrected in this erratum.
