DD is PT, and when I'm out w/ her shopping, I don't want her to sit on toilets in public places. What do you do? Do you carry a portable potty w/ you and have her go potty in the car? Use those potty inserts on top of the adult toilet? So far, she just goes in her pull-ups, but then that's taking a step backwards. Do I hold her legs up facing the wrong way? Have her stand and squat on the toilet? Please any advice and help. She's 3 1/2 and needs to be fully PT b4 her sister is born in August. TFTHIA
