my dd is almost 18 months. i've noticed she has been keeping to a "potty" routine such as holding it during naps then going after she wakes up, etc. i've heard this could be a sign of readiness for potty training but i'm not sure. she's my first baby so i'm not sure how it works. i know not to rush it and she'll do it when she's ready but i wanted to get an idea of what to look for. so how did you know your LO was ready for the big kid potty?
