When to try big girl undies? FTM

Nash • 👩‍👩‍👧‍👧 Mom of 2 👧 👶🏻

My daughter is 2 and uses the potty for poo 90% of the time. She will stop playing and walk to the bathroom, we’ll ask what she is doing and she says “sitting on potty”. She does not do this for pee yet. Should we try big girl undies during the day so she gets used to the pee sensation? I don’t want to rush her but at the same time she seems ready?

What did you do?
