When did you start potty training your babies?

Mom said nagpotty train sya samin 4 kids nya when we were 2yrs old. Plan ko narin simulan sa daughter ko who's turning 2 sa Dec. I can see that she's showing readiness na to it when sometimes nakapanty lang sya sa bahay and nagsasabi na na-wiwiwi or poop na sya.. YUn lang medyo late na - nagawa na nya. hahaha!
