I make and give baby quilts to friends expecting them to make the right choice in its use. My own children did not have a quilt or blankets in the crib with them until after 6 months. Most advice is no blankets until after a year, when baby moves to toddler bed. Baby quilts are for when holding baby, and playing on the floor, and for taking pictures, and... Not for 'in' the crib with baby. The link below has more info from the VP of public affairs for the SIDS Alliance.
