How long does it take for a tooth to come in??

Well thats my question how long does it take for a tooth to come in??? Seriously we have been working on this thing since tuesday!!! Poor baby!!! Shes done so well this weekend i'm so proud of her!!! Shes started to army crawl across the carpet!!! We have been doing this since monday the 10th!! She used to only move for her cell phone but now decided that she like that better than rolling from point a to b!! Its very exciting to see her learning more and more everyday!!! Her daddy just laughs and tells her he's NAVY not ARMY so she can't crawl like the other branch!! Todays lunch was special we had cheese cubes, toast squares and yogart melts!! Were trying to get her to start eating some finger foods!! Well all is going well, I have some more pictures I need to upload!! Jadyn got a picture with some samons!!
