I expect everything out of them that they can handle without negative effects. If they can do it, they should do it. That is of course allowing for what they can handle. Every kid needs time to play, be loved, learn, and just be a kid. But I do believe it is never too early to start responsible habits and the understanding of responsibility. You are under no obligation to sit down and play the way he wants to play. I once heard that quality time is not the amount of time, but how it's spent. A five minute story that you both enjoy is better than 30 min. of floor time that is a power struggle and really not any fun. Floor time can be great though if you get creative. You can also make it educational. especially if they don't realize they are being taught. When my kids are being overwhelming in attention. I tell them honestly that I love them very much and I like doing things with them, but sometimes every person needs some quiet time. We can play in a bit when and if....I honestly don't know how to tell you what consequences are appropriate. Some things work for some kids in some situations. I do know that the times I have problems are when I am not in control of my emotions like I should be and my execution in manner of dictating, speaking, guiding, etc. to them is not controlled. My kids only get spanked when they are doing or have done something that can have a devastating effect. Something life threatening for example. They are very well behaved most of the time. I am realizing that the more i'm stable, consistent, and in control of myself, the more in control i am of them. I don't let them stay up late either. I hear of a lot of parents keeping their kids up until the kid is so tired that they want to go to bed. I think that is unhealthy for the child because they need a certain amount of sleep and will push the limit as far as they can. I also think it's unhealthy for the parents because that is a needed break from a lot of stress. My kids go to bed at 7:30-8:00. no later. they are 3 and 4. I know I sound like I know what i'm doing, but what you are feeling is something i am far too familiar with. Read some of my other posts. I think every mom on the planet gets so overwhelmed and thinks so badly of how they are doing. It will pass.
