Definitely not too early! We taught my daughter some sign when she was little so even if she couldn’t say she need to go potty she would sign it to us. She was potty trained by 18 months. My sister and I are 15 month apart and my mom didn’t have two babies in diapers at the same time.
No such thing as too early! It’s worth a shot (: potty training has no age guidelines it’s all about child’s readiness, parental preferences & privileges of time & space! 🫶🏼
It's never too early! And if she has that kind of awareness, it might not be too hard. My 9 month old is learning too. Before 2 they sometimes refer to it as elimination communication
