My 2 year old showed interest in her potty chair very early, and we have always been open and accommodating about it. We don't force her to use it if she doesn't want to, and I haven't really started "trying" to potty train her. I've been kind of lazy about it and letting her go her own pace really, which is probably for the best anyways. I don't want to push her before she's ready. She goes before bath or showers and sometimes she'll join us in the bathroom and go with us on her potty. Other times, she'll completely take off her pants and diaper, pee in her potty and dump it out in the toilet and flush it. She even wipes. She's definitely got the idea down.
She's at the point where if she isn't wearing a diaper (she's too skinny for pull ups or for underwear since she's all of 20lbs :-/) she'll pee in the potty and she'll let us know she has to pee or poop. However, whenever she sits on the potty to poop she gets nervous and can't go. I helped her down many times and when she said she had to go I helped her back up, but eventually she asked for a diaper and I put one on her. Within about 5 minutes, she didn't want to sit down in a chair and told me she'd pooped, so I know she really did have to go.
My question is, where do I go from here? I feel like if I started being proactive about it we could probably make a lot of progress toward keeping her out of diapers, but I don't know how to approach the poop issue. I know it's pretty common. I don't want to create a bigger problem about it. Also, I'm 11 weeks pregnant, so I worry that when the baby comes she'll feel the need to regress back into diapers if she completely potty trains close to the end of my pregnancy.
I don't mind the diapers, and I'm not in any rush, but I don't want to do her harm by waiting too long either.
Can you all offer some advice? :)
