My girl is potty trained at 1 yr 4 mos. Sadly, it was yaya who trained her. Binabasa facial reaction ni baby tapos lalagay na niya agad sa potty trainer niya. Siguro she was 1 yr 2 mos that time.
To other sisters whose son/daughter is not yet potty trained, ok lang 'yan. Average daw is 3 yrs old, accdg to my pedia. Also, I think the other pedias have a checklist to check if you're baby is ready to be potty trained na.
