The main thing to say about potty training is, “Take it slow and don’t over stress or over push.” This aspect of parenting is often very stressful to parents and kids alike, but doesn’t need to be so.
You can start slowly at this age by having your child sit on the potty at “common sense”times like when they wake up, before a nap, before bath time and before bed. Once they’ve gone on the potty a few times, you can increase this frequency and take them to the potty more often.
It’s fine to use a little potty, but the inserts that fit on regular toilets also work well and are much easier to keep clean.
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.
