No Lisa, it wasn't you!
I agree we should probably refrain from spraying anything on the blankets for the babies' sake. I'm willing to wash them before I donate with unscented baby detergent. I don't have kids but my dog has really bad allergies and that is all I can use on his bedding with out causing him to break out in hives.
To air the blankets that I have gotten that smelled like smoke I put out on my clothes line during the day and let them sit overnight in my sunroom with the windows open. It seemed to get rid of the smell. I try to avoid using chemicals when ever I can due to my own and my dog's allergies. I sun/air a lot of things before trying anything else.
