I have a 9 y.o. DS that since he was very young was in our bed. We tried for years to get him to sleep elsewhere. When he was born we kept him in our bed but when he was old enough to crawl we placed him in a crib next to our to keep him from falling off.
Then when he was a bit older around 4 he would have some strange behaviors and would always end up in bed with us.
We dealt with many issues but I thought they were all growing
stages. Finally, when thing seemed to be out of control I sought help It took many tries but we found out that our son was Bipolar and ADHD.
In Bipolar children they will often dream in blood and gore and have horrid nightmares. Many times they can't explain these.
Now I know why he was afraid. This explained alot.
He is now on meds and they help a great deal but he is still prone to come to our bed when he feels afraid and it's OK with us. He is now also able to explain and express many of these dreams and they are enough to scare me.
Could there be an underlying issue(s)?
Not all kids are going to have problems like we have but usually if they are doing things like this they have a reason and it may not be something the child can explain. He may not even know why.
It may be just a "feeling" he gets.
Be patient, I realize it's hard. Try to look beyond the hassle. I've slept on the couch or spare bed many of times so that my son could feel secure.
Best of Luck!
