I always keep Babies at 2 days (lowest it will go) no matter the lifespan I'm playing. That's the closest I get to skipping. I have been known to cheat needs ignoring them until the birthday notice appears.

User-Directed Scolding + Other Punishment Tweaks Mod Description
This is a script mod tweaking parts of the punishment system from Generations. It will warn you with a pop-up whenever game tries to force a sim to scold a misbehaving child/teen so you can to stop them if you wish. (It even lets you turn off the whole forcing to scold feature altogether if you choose)
The mod also adds a custom Punishment... interaction menu on all child and teen sims that lets you choose the type of punishment to perform as and whenever you see fit instead of letting the game decide for you.
It's pretty cool! I use it... took me a while to give in and finally install it after seeing it on the front page so many times. Now I'm glad I have it because the grounding system is a bit broken. This mod lets you be in control (and then some).
