Jonathon Dylan Sachs (born January 19, 2005) is the second and youngest child of Greg and Fanci. He has an older brother named Ryan.

He appeared to be much more well behaved than his brother, although he can be just as stubborn during bedtime, and he has a tendency to hit. Greg said that he picked up on his brother's behavior and copied it.

He was 3 (almost 4) years old at the time and is now 13 in 2018.
