When my son was almost 2 he showed an interest for about 2 months, then it switched. Typically, dad's are going to have less interest in potty training. Stereotypically, the dad is the one working outside the home and it's the mom's "job" to take care of stuff like that. it's also a detail thing, and guys prefer the big picture. (just pee and be done). so you will probably do the lion's share of potty training.
what worked best for us was to know there are certain timings that you could pretty much count on for "potty times" and if we made sure to hit those and then check periodically between, our actual potty training period lasted aobut 3 months (when we hit it hard and didn't slack back off when he should little interest)
Morning when he wakes up
about 30 minutes after breakfast
mid morning
about 30 min. after lunch
after waking from afternoon nap
about 30 minutes after dinner
Just before bed
For our son, it's very hard to go to sleep at night or nap if he hasn't had #2. Especially at bedtime. If we put him down before, then he wrestles around until he either gets up to go or sometimes just falls asleep from being very tired.
Once we defined potty breaks, rather than "whenever you have a moment" it seemed to make the day flow much better and was more routine for him.
