3 year old still wearing nappies!!!!

Hey ladies. I feel like this is my failure and I am not happy about it...but need other's opinion, input who have older children.

Have a 3 year ( + 3 months) old girl. She is clever, developed well, speaks well. Never had any issues at all.

Started toilet training 1 year ago!!!

She goes to nursery and enjoyed going to the toilet with her friends there. Had some setbacks but thought she was progressing well the first 5-6 months....

Than she refused to go to the toilet at home!

I have a Minnie Mouse toilet seat that she loves. Bought Huggies Pullups for toilet training. Talked about it with her a lot. Introduced incentives...than she refused to use the toilet at all!

Meanwhile I was 7 months pregnant and to be honest I kind of gave up on it as well as pregnancy progressed and had my baby....

Now she is in nursery again ( had a 3mo th break) and sometimes she uses the toilet in nursery but again at home she doesn't wee in the toilet.

I tried putting her in knickers. She wets herself.

Talked to her about it million times.

Today did the same thing and she wet herself 2 times.

I am so annoyed! But got to think she has issues?

Asked her if she feels when she has to wee? She said NO.

Repeated the questions the answer was the same.

However asked her if she doesn't want to go to the toilet or she cannot go? She said doesn't want to.

Now I really don't know what to believe. How do I get her to use the toilet?
