if it is done now, i would cold water wash with cold water (don't even warm water rinse, change of temp can make felt easily) rinse and give her a little tag with the same info... if you put that wool bat into a dryer while it is wet, it will be felt when it comes out...it should be air dried... in future, use poly for baby quilts, washable, dryable, hypoallergenic and dragable for years..allergies are too prevalent in young ones and wool is highly allergenic to a pretty big percentage of people.. i'm sure it feels wonderful and looks beautiful so we're all gonna cross our fingers...i know your daughter will love the quilt...
