He seemed like a typical preschooler, very active and in need of boundaries, but not as badly behaved as other Supernanny children. Like Beau, he didn't stay in his bed.
Although Leo didn't act out as much as Beau, he got sent to timeout once for slapping his brother (Beau). He was very easy to be dealt with during that day unlike other "Supernanny" children because he didn't escape from timeout and he actually stayed there for his time. Then he told Beau he was sorry.
He was 4 years old in 2008 and is now 13 and will be 14 in 2017.
