My DD1 is pretty much the same, well worse really as it has been going on for so long.

Consistency and following through it a big thing. Something both DH and I are a bit slack on. We are good for awhile, then fall back into old habits. Sleep is another big one, the worst behaviour comes from being overtired, especially if she is hungry.

The other thing is how occupied she is. DD1 gets quite bored, she has a huge imagination and is quite physical. Due to DD2 she can't do a lot of the things she likes. She loves craft, but DD2 just messes things up. She loves the huge slides at the park, but if I take her I have a very stressful time dealing with a miserable DD2 who just can't do the same thing as her. I dearly wish Kinder had more hours, she needs so much more than what I can give.

Oh, almost forgot. Try being proactive, rather than reactive. I am not the most organised person, so often I wait to the "I'm hungry" before organising food. Not a good thing. I have had better days when I have been prepared, looked at the clock and thought "morning tea time". Same with activities. Normally I would just go and hang out the washing or into the veggie patch expecting them to follow me out. That just ends in disaster, I am called in all the time, then when I need to be in, they want to be out. So now (well I try) to give them warning to get boots on, we are going outside. If we are having a home day, then I give prior warning. If I think the week is going to be too quiet, like I know we will be home all weekend, then I try to organise a catch up with one of her little friends.
