I started to potty train my daughter when she was 18 months...but then again she was showing signs of being ready (ie. waking dry morning and nap more days than not, holding herself then peeing in her diaper, sitting herself on her potty with her clothes on, etc.) There were days when she had more accidents then times she peed in the potty but that subsided in a month or two and now at 2 (just had her birthday 3 days ago) she is pretty much day time potty trained. We only put a pull-up on her if it bed time or if we're leaving the house. She willingly uses the potty while we're out and it's great! No more dirty diapers for this mama!!!
