DS is 21 months old. He is a good speaker and understands commands and likes to help around the house. We play alot and I talk to him all the time telling him what colour things are, where we are going, what we are doing, how many of something there are etc. He has been sitting on the potty and doing a pee. No number twos as yet. We do the potty always at bathtime, in the morning when he is getting dressed and when he is getting his nappy changed. He is still in his cot and uses a dummy to sleep with, no other time. What else should I be doing for him developmentally? Should we be transitioning to his cotbed? Should he be drinking from a normal cup? How quickly and how do we move on with potty training? I get a bit paranoid when friends do things with their children and I haven't (friend moverd her DS into a bed a few weeks ago). Just worried I should have more of a structure to make sure things happen for him.
