Signs that he’s ready - can stay dry for at least 2hrs, shows interest when u go toilet, can pull pants up and down, and understands simple instructions. Not being able to verbally tell u is ok, some kids show physical cues like squatting or going quiet instead!
For tips, what worked for my lo was the 3 day method - clear ur schedule for a long weekend, let him go bottomless at home and bring him to the potty every 30-45mins. Lots of praise and small rewards when he goes even a little bit. Accidents will happen dun scold just clean up calmly. Also try letting him pick his own potty or undies, makes them more excited abt the process 😊 jiayou u got this!!
