I have a 2 yr old dcg and she speaks and understands pretty much everything I say or ask her to do. In the last week or so, she has stopped following direction. For example: I will say "xxx come here please", or "Come put this away" etc... Instead of doing as she was asked, she will just look at me with a kind of snarky smile on her face and sometimes even say "no" and will also sometimes laugh. I remind her that she is being rude and then ask her nicely again to "Come here" and she will continue to just look at me and smile. After me repeatedly asking her nicely and politely to do as she is told, I walk up to her and take her hand, and walk her over to where I originally was and tell her in stern voice that I wanted her to come over here and that I would like her to listen, etc.... I'm not really sure what else to do in this situation as she is still young (turned 2 last month). What have others done in a situation like this? Is there something else I should be doing or saying to her to get her to listen and not think that it's a joke?
TIA
