Anyone know why Baby Calm was discontinued?

Hey guys!
I use to use this product called Baby Calm with my son when he was 2 or 3. I was recently looking for it again for a friend and noticed it is no longer available. Does anyone know why?

Yikes it was nice to have something natural to help your little one sleep, my son needed his tonsils and adneoids out when he was young do to sleep apnea and when his surgery was done and he was healed, he was still scared to fall asleep due to past experiences. But this helped him so much.

We are using Homeopathic Calms Forte, it is natural and wonderful! Hope it helps. And I just found a website where I am able to get it with great discount: http://www.vitacost.com/Hylands-Calms-Forte-4-Kids
