NO, No and No

So my darling daughter is on a no, kick! Trying not to overreact when she says it! I dont want to give her attention for it or she will probably enjoy that and do it more. However I am trying to encourage positive behavior and introducing the word No thank you! Hmmmm so this is the newest behavior that I'm observing and deciding what the most effective response from me will be.

However she is learning so quickly and for the most part she always uses please and thank you. She has started calling her papa granpa with out any prompting. She knows about 23 of her letters! She is struggling with colors! Shes also the most precious blessing ever!
