Hi. My LO is nearly 18 months and she has learnt how to undress herself including her nappy (she is now in pull ups). does this mean that she is ready to start potty training? Everytime we think she is going to do something we ask her sit on the potty which she does really nicely but she wont stay on it for long. A few times she has sat down then got up do a poo. Sometimes we wont even sit down, will throw it or play with it. What is the best way go from here? Many thanks
