I'm so glad you are having success with your weighted blanket!
DS has been using his weighted blanket for just over a year and we still love it. (He has an 8lb twin size.) DS does go through phases of sleep difficulties, but overall the weighted blanket helps him sleep through the night and sleep in his own bed. It has made a huge difference in our lives.
We take the weighted blanket with us when we travel (we travel by car, so packing is not an issue). It has been an amazing help for getting DS to sleep well in hotels, at relatives' houses, etc.
The blanket is still in great shape despite constant use, repeated washings, and even getting vomited on. It has definitely been worth the investment for us.
