my daughter just turned 21 months and i think she might be ready to buy her a potty. I just read to her today the "once upon a potty"book. she says she wants to do pee pee on the potty like her big brother. I just don't want to start to early with her. i started at 2 for my son and it took almost a year for him to figure out the "feeling" on his own. he would go when i put him on the potty for 10 months to figure it out on his own.i know girls are easier, but not all girls. so she has just seen her brother doing it the last year. so i think she might be ready to start trying.
