Dh and I have innies. Ds1 and Ds2 have outies. Which made me wonder...do outies turn into innies as you get older? Or is it once an innie always an innie, and ditto with outies?
Most kids these days seem to have outies but I am fairly sure mine's always been an innie (apart from when pregnant when I emerged as an outie, and it didn't feel right at all). Do they fasten off differently these days?
Of such stuff great philosophical questions are made.
