I have only one potty trained child so far since my daughter is just 16 months old.
My son who is now 3.5 years old is finally potty trained. We started at 16 months. He was always interested in the potty and liked to be in the bathroom with us when we went. I would take him to the potty every couple of hours, when I went, when DH went, and about 30 minutes after a meal. So it worked out be about 1-2 hours throughout the day. It was hit and miss. If he was sitting on the potty at the right time, he would go. We did this for about a month.
Then I got pregnant with my daughter and was so nauseated all day that potty training got put on the back burner.
At 19 months my son started preschool and that really kicked potty training back into gear since they would take the kids on a regular basis to the potty.
But honestly, although my son had the physical capability to potty train at age 2, he didn't really "get it" until just before his 3rd birthday. Only then would he go on his own when he had to go. We still remind him to go before we leave the house and before bedtime and we will still see him doing the "potty dance" at times and have to practically force him to the potty when he is engrossed in something. But from age 2-3, he would usually go on the potty if we took him, he just didn't recognize the sensation of having to go on his own until just before he turned 3. Now at 3.5 we are almost at the stage where we can get rid of the nighttime pullups as he is getting up on his own (at the wee hours of 5 and 6am) to go to the potty in the morning on his own.
I also thought I would get him potty trained at an early age, but my experience with my son has taught me to really rely on my child's cues. If I did that from the get go it would have saved me a lot of stress and frustration and time on the cleaning up the accidents.
Now with my daughter who is 16 months old, she definitely isn't ready to potty train yet. My son was always on the fast track developmentally (teething at 4 months, crawling at 6 months, walking at 12 months, talking at an early age, etc.). My daughter is on the slower side of things. She takes her time, but when she gets it, she learns things FAST (crawling at 11 months, teething at 12 months, walking at 13 months, talking at 15 months, etc.). So I am hoping that within the next 6 months or so she will show an interest in the potty (she always goes to the bathroom with us whenever any of us have to go) and hopefully watching her big brother and some of our friends kids going to the potty will help her get interested in it. But if not, I am not going to stress out about it.
Like my pediatrician said to me once "Most kids walk and talk by age 2, and most kids potty train by age 5, so don't stress about it."
So give it a go with your child, but if you find yourself getting stressed or your child is getting stressed about it, take a break and try it again a few months later. Eventually with repetition and when they are ready, your child will potty train.
