My daughter turned 2 in April. Started potty training her about 2 weeks ago. And she got the hang of it within the first 2-3 days. I'm really happy that it was so easy, and quick! (I also have a 4 year old) And how I started the process was w my 2 year old was Letting her during the day walk around the house naked (because takin pannys/pamper off was to much for her, it was quick starter off for her to understand to use toilet instead worrying about taking clothes off)and kept asking her if she had to pee, sometimes she would fool me but sometimes she would actually go. (She had baby toilet) I was scared to take her out the house and her have a accident. So I would put her in pannys still (leaving house w pamper FOR ME, was letting her still think it was ok to pee in pamper)(so I left house in pannys)(feels different to her) and constantly ask if she needed to pee. (We didn't leave the house much so we had a lot of practice at home already) she got the hang of it in 2 days. At night time (around 9ish-11ish) I'd make her pee before bed, so no accidents through the night. I'm still amazed that she wakes her self up and wakes me up in the middle of the night to tell me she has to pee.... she had a few accidents on the pooping part like 2 or 3 times( they say the pooping training part is a lot harder) (wasn't for me) and I would just get onto her and tell her that was nasty and she couldn't poop her self , she HAD TO USE TOILET I would say to her! She talks so much. Even sentences, big words, knows all her abc's, counts all the way to 10. & can sing the whole song (twinkle twinkle)(daddy finger)(itsybitsyspider) I think she's really smart for her just berly turning 2. My other daughter that is 4 is completely different, she still has accidents at night time, and wasn't much of a speaker till a little after 2.
