Jon's new age

Because Jon didn't say which age he was regressing and when it stopped he looks like he is 6 months and his room then begins to change because it now looks like a baby nursery. His phone had transformed into a baby monitor. His mothers body had changed also because she now has larger breast and that her clothing has changed because they are designed for breastfeeding. Now Karyn was Jon's babysitter while his mother was working.
