Agree it's not potty training, but potty learning or potty timing. I'm a big fan though.
My DD started on potty at around 10 months and was fully clean and dry by 22 months (clean by a year in fact)
I started DS at 9 months. He is now 10.5 months and totally knows what a potty is for. We put him on the pot at every nappy change, especially first thing in the morning. This is really successful because he used to wee himself out of every night nappy, but now often it is obvious he has only wee'd once in the night and we even had one dry nappy one memorable morning. This is a boy who still has at least 2 night feeds!!
In the last couple of days he has started using the potty sign we use (he is a big fan of baby signing and already has at least 10 recognisable signs). He isn't really able to hold on, but has given the sign when pooing at least so it's a start.
We use a big potty/seat/step thing. He can't get on and off by himself, but is more than happy to sit for 5 minutes+ and sing/read books/chat etc. To be honest though we usually don't have to wait that long because he now relaxes his bladder/bowels almost as soon as we put him on it.
BTW I'm not mistaking this for real potty training - it could be months/years before he is out of nappies. However if it gives him the opportunity to stay clean and dry and he is not protesting; and it gives me less nappies to wash - then I'll remain a big fan.
One of the most important things to remember doing it this way is to make sure it is entirely done within the babies own comfort zone. There should be no coercion, cajoling, anger, shouting, blame. If they don't want to sit or maybe they start using nappies again then so be it. All you are doing is giving them an opportunity, it is up to them to accept it or not. To do otherwise might risk giving them a big complex about training.
Trust your baby!
