Some kids/people are just this way. There is not a lot to do about it, except accept it and take it into account and be patient and loving. He very well may have a Sanguine Temperment and if you have a Choleric Temperment - well they just don't mesh all that well. Everyone comes in with certain temperments no matter the environment. Yet this individuality, heredity and environmnet meet and influence each other. There is no good or bad temperment, each has their own negatives and positives. Sanguine temperments are very flighty. They usually can't stand repeition and although easily aroused by something different or exciting it quickly loses it's strength and disappears. They're like a butterfly floating here and there and every where or some might say it's more like a little nat buzzing around. The point is they're hard to reel in and keep them paying attention. They cannot help themselves. They live on nervous energy and therefore with this "type" it's important to keep things simple and orderly, so their nervous system can rest so to speak. This is especially important in the bedroom for restful sleep. Sanguines have to see and look at everything all the time, their attention darts here and there, tiring them mentally, hence the quiet, simple surroundings. A sanguine child can be very exhausting on parents as they require a lot more patience. Punishment means very little to them and guilt is fleeting at best. A sanguine child wants to behave but he forgets, actually forgets. They love to bring you happiness and so if you tell them something makes you happy or pleases you, they will continue to try and bring more happiness. For the sanguine the love felt is the biggest motivating force around them. --- Again, I don't know if he is this temperment and it's too early to tell, but often we can see signs even at this age. Knowing your child's temperment and understanding the temperments and how to utilize such can be a powerful tool in the household.
Sanguine is also the phase of life he's in, which will continue till about 8 years old. It's hard to say what a person's temperment is until they reach about the age of 8. We all have one that is promnient and another that is secondary, but we all have all four as well as different phases of life which are indicative to a certain temperment. The temperments are expressed by psychological and physical characteristics. You may want to look up the four temperments, you may find it interesting as well as imformative. I've read several books on the subject and know people who know much more than I do. I've noticed a lot of the sites on this subject leave much to be desired, but there are some descent ones too. Just thought I'd share this as it could explain a lot. Have patience and just love him as he is.
You might want to try meeting him eye to eye when speaking to him more often. A lot of times people who are this way just don't hear you because their mind is on what they think it is instead of hearing the directions. They're caught up in their own thinking processes. Just like when he kept looking on the desk where the tissues would usually be instead of the floor where they wouldn't usually be. He couldn't hear floor bc it should be on the desk.
p.s. sanguine temperments aren't the easiest for me bc they're out of this world most of the time. But do know he is in this stage of life and if he is a sanguine, they grow to be fine adults just as anyone else. (I know this is awfully long but hope it sheds some light on the situation)
The Best to you and yours
