When you LO is ready. I try on 2yr 8mths she cannot hold her urine yet. So failed. 3yr 3mths she was all ready.. With a diaper but will control and go toilet and we trail with diaper for a week. The following week we go diaper free!! U will know the best for your LO. Every child is different. We can take online or other as a guide but not compare. 😉
I started the moment my baby turn 10 month. Still training but her shitting time quite regular I let her know that potty is for shitting.
started my LOs after 3.5yo so they caught on very quickly
