Hello H.,
yes, i dealt with sleep issues as well as several couples that attended parenting classes in my home. I know this may sound strange but when your husband comes home from work be sure you and him have what we call "couch time" this means you and him go off to the side, the children may be present in the room but they are not allowed to interupt your "couch time"
"couch time" may only take 15-20 mins. But this is mommy and daddy's time. This builds security into the child. They are able to watch mom and dad communicate, laugh, share time together. When you are through let them children know mom and dad are available for them.
Hope this helps. It did for many of us. Even those who were at their wit's end!!!!!
