Mina you have to go potty?

Andrew wants to help out so much. Kristy is trying to potty train Mina. She is a little scared of the big potty. But she is much better with her own potty. Andrew was trying to potty train Mina. He kept asking Mina if she had to go Potty. Andrew would walk her over to her potty. The first time she sat down she was a little wet. I asked him to get her a diaper he came back with big girl underwear he said "Mina wants to wear big girl underwear." then he tried to help her put them on. That did not work out that well, but it was cut. Then Andrew brought her back to the potty and told Mina. To pick up the lid, pull down her pant, and she did. Then she sat and actually went potty. He kept asking her the whole rest of the night "Mina you have to go potty, Mina you have to go potty, Mina you have to go potty?" over and over. I am a little surprised she did not get mad at him. I was getting a little annoyed with it and he wasn't even asking me. He want to take care of everything it is great sometime. And others not so much. He is my little helper.
