I just had this thought today..maybe I could try TTing Becky? TBH, I don't want to

It's too much work for me right now (well putting a nappy on while she's running isn't the easiest task either), I'm having a lot going on as it is so I'm not sure I want to do that. And I love nappies too much
I read it somewhere that its not worth TTing bubs under 18months old (Becky is 17 months)because they're simply not ready. They also don't suggest doing it in cooler months, so doesn't seem like we'll be doing it until later this year? She will be over 2
She is almost toilet aware..or so I believe. She's telling me when she has done pee or poo (only during nappy free time, but I can tell if she's pooing in the nappy). She will look down trying to see her products even if they haven't come out yet

Does that mean she's aware?
Should I try TTing her? Or should I wait until she's ready? but how do I know that she is? And how do I start if I decide to TT her?
Tell you what..this is a lot more confusing than starting cloths
