Oh, yeah, do I!
My daughter has been stalling bedtime and also coming into our room every morning between 5-6am to sleep with us in bed. She also is VERY bossy, and she is in that stage where a rule for her is considered a rule to us. So she will repeat things we have said to discipline and also she has started a light tap on the leg and saying she is "mad" when she is disciplined at times.
Good thing is, I have figured out the stalling bedtime thing, and the last 3 nights now we have only had 1-3 outings from the room. She doesn't have to sleep at bedtime, but she has to stay in her room. She can come out to use the washroom, but that is it. I'm wondering how to deal with the early morning wakings right now, not quite sure how to proceed. She typically comes in when her dad is already awake for work in the morning. I am going to be doing time outs for "hitting" and other bad behaviour.
It's definitely a tougher age than 2 for us. I feel like 1-2 has been the easiest by far.
