You are so right!!
He does have BIG feelings. I don't want to prevent them as much as I want to understand and guide them in a way that is godly and convenient for him. I don't want him to have problems at school and be labeled the problem child. I know he is only 2 1/2, but I am a teacher (2nd grade), and I see this happen daily.
Does changing my mind give him a feeling of uncertainty or inconsistency? I feel I change my mind because, as you said, I say no because it's inconvenient, not something I really mind. Thank you and I apologize if I'm bombarding you with all these questions, he is at an age that honestly, I just don't know what to do 70% of the time.
