I make all baby quilts to be toddler size.
My DD is a RN, started out as charge nurse for Labor and Delivery, now a director of a hospital. She used baby quilts I made to cover her babies in the crib. She also had two of the instant no breathing/movement detection mats devices in the crib. The baby was never off them with two of them covering the whole mattress. I don't know of any newborn not having the detection mats in their crib now. The church has them in all the cribs in the nursery.
