Potty training tips for almost 3 year old?

Brianna • Calvin born Septemeber 15 2016

He goes pee on the potty only if I ask him every so often if he has to pee.

How can I get him to vocalize he has to potty? He talks VERY well (he is the size and has the mind of a 4 year old).

Also how can I get him comfortable to poop on the potty? No matter what I try he will not poop, he only will standing up in his diaper/pull up.

He’s in early headstart and they’re required to be fully potty trained when they’re 3 so the can move up to the next class which he’s all set to do minus the potty training still.

He turns 3 in the beginning of September! Thanks in advance
