  • * Ten of 84 cases with unspecified bedsharing status were considered to be nonbedsharing.

  • ** Three of the 30 bedsharing infants were excluded from weight-related analyses because they were sleeping with someone other than the mother. One was omitted because of missing weight information.

  • Large designates pregravid weight ≥79.5 kg.

  • Small designates pregravid weight <79.5 kg.

    One woman in each bedsharing group had unknown weight.
