My daughter is two, so we of course gear towards her particular age. With an older child, consequences can be later on, but with a two year old, they must be immediate.
My daughter sometimes doesn't want to get dressed and ready in the morning. Most days, this doesn't matter and she can get ready when she feels like it. On other days, it does. If she doesn't want to get dressed, I tell her. "If you don't get dressed, we cannot go to the park."
Here's the really important key- as a parent, you have to be ready to follow through with the consequence. If I absolutely need us to go somewhere, like a doctor appt, I can't use this type of consequence. I'm still personally working through those cases, but I have found that I have more success telling her how it's making me feel when she isn't cooperating. "I would really like to take you to the park. It makes me sad that you don't want to get ready and go. I like to swing you and go down the slides with you. If you don't get ready, I will be very sad that we can't go." Sometimes, that does work.
As always, I love positive reinforcement and it's typically my first choice. When she doesn't want to get ready, I will offer something if she does what is being asked of her. "If you let me get all your clothes on and brush your hair without fighting, then we can stop at Jamba Juice after grocery shopping." It doesn't have to be a actual object. It can be something like going to the toy section of the store to play for a while after finishing shopping.
For me, consequences must be age appropriate. While a 7 year old will understand something like "If you don't do x, y or z, then tomorrow..." a toddler does not. So, it's important to tailor consequences to the developmental age group.
