Hi E., I just read your post. I have some questions for you. 1.How long has your son wanted to sleep with blanket around his neck? 2.I belive you said ,when you take the blanket and explain why you don't want him to wrap the blanket around his neck,he then wants covers pulled up around his neck.I would need more specifics about you, your life,your son,the father, however, I will offer some suggestions. Since your son will sleep without the blanket,( and will take some thought on your part), is it possible to keep the baby out of the bed ?,so that would not be a problem.Or would your son like to sleep on the floor which you could fix it up just for him because He is the "big" brother.Do you use encouragement rather than telling him what he should not do?,for example:you are doing a really good job of not sleeping with the blanket around your neck. I think since you are being cooperative with mom,I have an idea,what do you think about finding something really special for you to sleep with. Give him 2 choices,(maybe a new bear ,it could be inexpensive,or if he already has a couple of soft or stuffed animals,he likes ,if he chooses one ,then make it special, great, that's a good chioce. Then you could say ,do you want to do something to get the toy fixed up, like ,maybe pajamas ,maybe a night cap?,let him be apart of the new project,countinue to encourage ,don't be disapointed if he refuses,you can say ,ok , maybe you will tomorrow.(talking to him at his eye level,as much as you can, especially about important things.) We don't want to give something up "we really like , unless we find something better. Active parenting helps the child learn more healthy developmental behaviors. don't forget there are many good books on parenting. Take care.
