LO just turned 3 and shows every sign of readiness and has for a long time. She stays dry even overnight, can verbalize when she needs to go, plays pretend potty, you name it. Is excited about pull ups and panties. But every time she tries to tinkle - nada. Over months and months she has succeeded about twice. I haven't pushed it, but often she refuses to try (so I let it go), I think because she's discouraged. I really think if we could get over the hump she'd train pretty quickly. She seems so interested in it and I just want to help. Any ideas??
