Absolutely refuses to potty train

Zachary was the same way about potty training. He acted terrified of the toilet and would scream at just the mention of going potty. We tried potty training at about 2 yrs old and when it seemed he wasn't ready, put it off for a few months. When we tried again at about 2.5 we got the same thing and after a few months of really struggling with him, decided to put it off again. A few months after he turned 3 though it just seemed to click one day and he wanted to go and we had him completely potty trained in a matter of a few weeks.
I know it is frustrating and hope that things get easier for you.

absolutely do not push her to go potty. It will help nothing. Especially with a new baby coming. Just act like you don't care one way or another if she uses the potty and I promise you she will start using it very soon!

Also, while in theory the doll looks like a good idea I think that having the doll drink out of a bottle sends the wrong message. You are trying to have your dd (and doll) act like a big girl yet the doll drinks from a bottle? I would think that would be confusing to a child. I dunno, maybe that is just me..everyone knows that I can be weird.

i had justin potty trained and then out of the blue he started peeing all over the place and is now back in diapers ... michael did the same thing..lex was the best at potty training she turned 3 and never had a problem...

I agree that trying to force her to use the potty will only cause more problems. I would just let her wear her pull-ups and ask her every so often if she has to go potty. If she says no, say fine and go on with what you were doing. Asking her if she has to go but not making her should start helping her to become aware of when she has to go and may make her more interested in going to the potty if it's not made such a big deal of.

As for cleaning herself, after she pees I think it's a good idea but after she's pooped in pull-ups, she needs help cleaning up. Using the potty is a big thing to learn but learning to clean herself is even bigger especially since she's a girl and you don't want her to start having infections from not being clean.

I'm assuming you have a little potty for her or a little seat to put on the big potty? My daughter didn't like the little potty much but wanted to use the big one like her big brother whereas my son was the opposite and preferred the little potty. I personally don't think the dolls are that big of an incentive. They're just another toy to play with but one may work well for you.

I say just be patient and in time your daughter will start using the potty. I know it's frustrating when you see younger and kids her age without diapers or pull-ups but just remember that each child is different. Once your new baby is born she may quickly decide that she wants to use the potty to prove she's a big girl and not a baby. Or she may regress. It's hard to say. I do wish you luck as potty training can be a very frustrating time for both parents and kids.

I used a movie Potty Time (by Duke University) for Brittany and that was the big change.

Trey I put a pull up on his teddy bear and that helped him to help his teddy go potty and show the teddy how to do it.

Ok....I am not saying this to be judgemental or mean because I have met you guys and know you are wonderful people, but I think sometimes you and Steve confuse her. I see from a lot of your post that sometimes you talk to her like she is an older child(which is VERY good), yet you sometimes treat her like she is younger. For instance...the carnaval, I know how scary it is to put your baby on a ride the first time and I know Kate can get excitable, but she can't learn to temper the excitability without the experiances and Steve and you can't expect independance if you don't give it. She doesn't get around children her age away from you and Steve so the teasing won't faze her because she can always get her encouragement from you guys, when her feelings get hurt it doesn't matter cause like every good parent we are going to try to boost their self esteem when they get picked on(and I think most of us do that). But with Kate the social world doesn't matter much because she knows she is safely folded in her own world within the three of you.
When I met Kate the first thing I thought was that she was going to be very outgoing and adventuring. She has a ton of spunk and a big independant streak. I think that she is behind socially because she doesn't really know whats expected socially. The pottying and language things are what she can CONTROL so she will. She knows it's what you want so she doesn't do it. She is very protected(which I can completely understand) but sometimes too much.
Basically because she is never away from you guys she doesn't have to care what the rest of the world thinks, and because she can use it to control her world she will. Did I make any sense?

As for how to get her cooperation I haven't much of a clue. When I decided to potty train mine I just made up my mind and did it. I ditched the diapers and only used pull-ups when we were going out and for bed. Yes it was messy and a PITA a lot of times, but it was effective for my kids. I didn't punish for accidents I just made them clean up and moved on. They got huge praise for going in the potty but not a whole lot of fan fare and treats, I just wanted it to become something they "did because it's what you do, not something they used to get something". I don't know what works for other peoples kids....I just know it worked for all 3 of mine and Anna when she was down here(I had her trained so that when she would get to our house she immediatley put on undies and used the potty....we would send her home in undies and she would always come back in diapers ).
Take heart that she will eventually "get it", or in Kate's case I think she will eventually just decide to find something else to focus on.....little miss stubborn that she is.

Don't push her. She'll do it when she's ready. I learned that the hard way with Darien. He was a couple of months over 4 by time he got potty trained.
