Just for future references, how young is too young to start potty training?

i had my son potty trained after his first birthday and before he turned two

i started mine at 12 month and he was almost potty trained until i got pregnant and stopped working with him. it all depends on your consistancy with baby and how you motivate him/her to use it

Every child is different and advances at different levels.

Under 1? I started my baby's at 2
