You don't say whether you friend is getting any support from any other family, like husband, siblings, or whatever. If she is not, she probably feels buried by all the responsibilities in her life, and is too emotionally numb to react to much of anything (specking from previous personal experience). See if she uses it or puts it somewhere special, give her time, and JeannieJo said, she may just have been speechless. Maybe give her the benefit of the doubt, considering her circumstances. Considerate friends like you may be what she needs to get through.
Your quilt is gorgeous!
