Eli was acting out a lot and finally one day he told me he missed me. With that comment I have made an effort to spend more time with him. He doesn't care if he has time with Daddy as long as he has a few minutes with me. So, he and I make sure that we have a few moments each day that are just his and mine. We also started giving him choices so that he thinks that he is in control. For example, waffle or cereal, tennis shoes or sandles, milk or water, red or green shirt. We only give him 2-3 options but he thinks that he is in charge. We also put cups at his level because he has learned how to get a drink of water from the fridge. When he tells us he is thirsty we tell him to go and get some water. He is so excited when he comes back having done that or something else. And lastly we took out tv and videos except on the weekend. There are no arguments in the morning or evening when we want to watch the news or something else. Just making these changes have stopped the major temper tantrums at our house. The hungry and tired tantrums still happen occasionally if I don't pay attention to the triggers. I forgot, we let him wake up Elly in the morning and he helps feed her too. So, again another responsibility as the big brother.
Good luck and as you said this will pass with time.
