Numb3rs Fanfic Finders

I'm pretty sure it was on fanfiction.net.  I don't remember much of the fic.  Charlie and Amita were together and somehow Charlie gets de-aged.  While he is de-aged I think Amita finds out she is pregnant and I think Charlie helps pick out names.  I think Don and Robin were together but I'm not sure.  Charlie does end up back to his proper age but I think he still sometimes de-ages.  In the epilogue I think de-aged Charlie was playing air hockey with his son and it also mentioned that Don at one point got hit by the de-aging whatever and sometimes de-ages like Charlie.  Sorry not more helpful but thanks in advance for any help.
