I've looked all over for these and I can't seem to find them anywhere. The links are broken for the baby hair and pores, and the teeth overlays are adfly links which I don't think work anymore, but please let me know if I'm wrong about that. I was able to find the file names for the baby hair and the pores through the Wayback Machine—baby hair is "s3m_babyhair.rar" (sorry, I don't know the names of the individual files) and pores is "pores by s3m.package". The teeth overlays I'm looking for specifically are the Teeth Gap ones and the Two Teeth ones for toddlers, but any extras would also be appreciated I do have the straight teeth braces though if anyone happens to be looking for those.
Thank you!

:O Wow thank you so much!!! You found a lot! You wouldn't be able to find the crooked teeth/crooked teeth with braces ones by Descargassims too, would you? If you're not up for looking then no problem, you've already helped a ton Thank you again!!

You're welcome I tried to find them, but they seem to be nowhere to be found. Glad to help!

I think I might have the crooked teeth. Please tell me if these are not it! http://www.simfileshare.net/download/4682467/

I believe those are it, thank you!!!

You're welcome! Alas I don't have the braces.
