Many kids are completely potty trained by this age. If that’s your child, great! If not, it’s not a worry yet at all. Many kids are slower and will continue to need patience as they slowly develop this skill.
Try to reduce pressure. Unfortunately if a child is feeling pressured to potty train, they often become resistant. This can lead to lots of frustration for parents and kids both and even lead to physical problems from avoiding going to the bathroom. Try to stay “laid back” and keep the pressure down.
If your child is in daycare or parent’s day out, talk to their teachers about what they’re doing at school. You may want to let the school take the lead in this area and copy their vocabulary and routine at home.
If this whole issue is becoming more and more frustrating, make sure you talk to your pediatrician about it for more individualized tips.
