NEED HELP TO POTTY TRAIN MY 29 MONTHS OLD BABY GIRL.PLEASE PLEASE GIVE ME SOME TIPS,IDEAS,SUGESSIONS.THANX.?

Seems like you have been through alot with this whole potty training thing. First off, I know its hard, but lower your stress level. Kids can sense when were stressed; and then they stress. And having a stressed potty trainer, not good. With you not allowing her to wear any nappies, that's a start. When she gets the urge to go wee or poo, sit her on the potty. If she cries, let her cry; as long as she's crying on the potty. It'll be hard, but worth it. She said she has to go, so, she needs to stay there until she goes. Sooner or later, it'll come out. And if she does get up, sit her back on the potty. If she messes up the floor, teach her to clean it. And do this everytime until she actually goes in the potty. When she does go, make a big deal out of it. Pick her up and swing her around, hug and kiss on her like crazy. And reward her with a little snack. Nothing big, just enough to encourage her to do it again. Reward her for the first few times, and then stop it. You dont want her to get the impression that she's gonna get something everytime. Good luck.
