maybe early potty training?

My first daughter was potty trained at 2 years old (thank god) and she showed me she was interested in the potty around 20 months .now I have a second one who is 17 months and for the passed week she has grown enourmously interested in the potty. she does the obvious signs of grunting and all that. If I asked her if she pooped she points to her put bla bla bla if I ask her were it is suppose to go she points to the potty (I am happy shes got the concept down because I know alot of children struggle with that concept) so I began putting her on the potty when I am about to change her diaper (with her cloths and diapers on) just to get her comfortable with the whole potty idea. who knows maybe early potty training?

My daughter was similar in her actions and fully potty trained by 18 months so I say go for it
