I believe that Robin was born in early 2013.

The writers had Chambliss trot out their timeline that 5 was two years post the 28 years.

So, in 2018, yes, Robin is 5.Neal is slightly older (but an unknown amount of time pased.)

Basically:

Season 3A ends like around March/April 2012....1 year, then 3B to 4B happens, then 2013, 5A happens and the year ends with 6A, part of 6B.
