What do you think is the best way to potty train a girl?
my daughter was potty train just after she turned 2. what i did was i would take her with me to use the potty. i would show her how a big girl uses the big girl potty. and show her that mommy wears big girl underwear and not diapers. then i would offer her the big girl potty each time. about 2 weeks later she actually used to potty. i figured she would learn better if she saw mommy using the potty. i did not use a small potty for her (i bought her one she just never used it) or pull ups. i also let her pick out a couple packs of underwear for herself. we only used rewards when it came to pooping in the potty. hope this helps
