Is this a tease???

My son, Caleb, is 19 months old, and for the past month is able to tell me that he has "poo poos" in his diaper. He will grab his diaper and say, "poo poos". I will check and 99% of the time he is right. My friend told me that he was ready to be potty-trained!!!! Is this a tease? The last three of my children didn't show any interest in potty-training until they were at least 3 years old!!! I am not the kind of mom that likes to spend months training them. I prefer the diapers and be done training in a day, like with Emma (she was 3 yrs 3 mos old). Caleb is not dry in the morning when he wakes up, so I am not convinced he is ready yet, or maybe it's me not ready to let go of my baby!!!! What to do??
