Hi there!
I have posted elsewhere about the Therific Naturals products. It contains Magnesium Sulphate and is a bubble bath you use to bath your LO in. I have a 5 year old daughter which I suspects have ADD as my husband have it. She had terrible dreams at night and were fighting all the time in her sleep. She often still sleep in our bed. I started bathing her in her after I heard some stories about the stuff. Must say, I didn't see an effect immediately as some say they do, BUT after a month now, I can definitely see an improvement.
If you don't want to buy the products, get plain comment Epsom Salt from the local store and test it. What is nice though, is that the Kiddy-Calm comes in 4 funky flavours and colours with BUBBLES.
I bath my 10 month old boy also in it. He goes to bed quite easily. However, try the following and get a good routine going.
Supper
Play until he is almost tired
Nice hot bath in Kiddy-Calm
Off to bed immediately with bottle or breast
Room dark with only night light
Say words like 'doedoe time' or whatever you use for sleep
Try the same thing for at least a week before you decide it doesn't work. Kids are very intelligent, they will test you to see if you stick to your guns. Routine are for sure boss!
The thing is less sleep will lead to more hyperactivity and more hyperactivity will cause less sleep. I am a firm believer that you have to know the signals of when you baby is tired and that he has to sleep as soon as he shows the signals. I am no expert, but can only share my experience.
Also, the book by Megan Faure and Ann Richarson titled Baby Sense is a recommended read regarding the sleep signals. I don't agree with everything they say, but regarding the sleep signals, I have practices it with my daughter and now son and it WORKED for me.
Try it.
Good luck and let me know
