@nicolebrittanyy: It definitely looks like they were stuck in some kind of none-aging state. As ZeekSlider says, you should only loose your relationships. Did that change ?
Did you try if you can age them via testingcheats ? Was this an pre-Gen game you were playing ?
@elijahhines10: Just to get it straight: When you do this in CAS in the beginning of the game, body hair works fine but when you use the cheat, it doesn't ? Is your base game still patched to 1.22 or did you revert that ?
@drake_mccarty: Do you have any pics ? I really can't imagine how that would look like.
@EatChees: Remove ALL mods and then try again.
@squiggyorb: Can you start your game directly ? There's a file called ts3w.exe in your game\bin folder (not sure about the patch on macs). Just doubleclick on that to see if that works.
@BreeSasha: As far as I remember, they changed that both parents get their wishes fulfilled if a toddlers learns to walk, whether they actually taught the little one or not. That might have something to do with it. Also did the Sim taught everything or did they switch ?
