She knows, has known and loves her son. We as our parents children mature, well, at the same time they do also.
Side note, i did much the same but would shread the panties and make sure they went in trashcan other than ours, oh what confusion would ensue, my mom would loose her mind looking for her panties and pantyhose. Good times, good times indeed.
All the best.
