I agree, I say wait awhile, besides, it's only the end of July, and you have several months before Dec anyways! My friend's daughter was about 4 or 5, she started taking her younger sister potty with her, and tryin to play Mom etc (my friend ran a daycare at the time, and her daughter was mimicing her when she was helping potty train kids) anyhow, it worked and that's how her youngest got potty trained! I think I pushed my oldest to much when he was around 18mo, and he's now almost 7 and still has accidents at night... My other son is the same age as your daughter, and all though he's a smart one, I couldn't imagine trying to potty train him now! (besides the fact boys can be harder). Just give her time, and she'll come around, also try the seat you can put on the big toliet if she doesn't care for the miniture potty! Don't stress over it, even though your oldest was potty trained that quickly, just remember each child develops differently! Good Luck!
