Hi M., I don't know the site, but I do know of two amazing (three if you count wearing baby out during the day, shorter naps or not letting the naps happen so late) things that helps me to this day with my troubled sleepers. Both are very safe for baby. First one is Homeopathic Calms tablets (they melt in the mouth posing no chocking hazards) and the other is called Badger Sleep Balm. You can rub this on their temples and third eye and they should be asleep in no time. The other thing that really helps us is no tv within an hour of sleep. The flickering light and amount of times that the screen refreshes itself in nanoseconds is too much stimulation for the little ones. I hope you find the site, there are many other ideas out there if mine don't work for you. Best of luck and hope you get some sleep.
A little about me...I am a single parent of twins who did not get any sleep for the first six months - I was seriously sleep deprived until someone gave me Calms for the boys. At six months I got my first full 6 hours of sleep (I usually need 8-9)
