RE: Is it too early to start potty training before 18 months?
My oldest started about that time. He would wake up dry so we did some encouragement. He would pee on the potty 95% of the time by his 2nd birthday and learned to poop on the potty by 25-26 months.
I did start with all my boys at 18-20 months sitting on the potty a few times a day esp mornings after naps and bath time. It worked well for us. I didnt push and followed their leads. DS2 was just before 2 1/2 and DS3 was right at 2 1/2. Night time took a little longer for them.
If your child is showing signs its not to young. Just follow his cues. Good luck!
