I am 7 years older than Michelle, only had 3 kids, do not have osteoporosis, and I have lost 2 inches in height. It has happened slowly, but one day I was standing next to my husband and he seemed so much taller. We measured my height and sure enough my 5'2" is now 5'.
Recently I visited my daughter (we are all fully vaccinated) and when she hugged me she said, "Wow, you HAVE gotten shorter."
Michelle looks really shrunken though. I don't think all those pregnancies did her any favors.
Just to clarify: I may be shorter, but I certainly do not look shrunken like Michelle d
