Dear @Carla, this pink loving womb- idea is superb and too much creative. 
Although, me too is very fond of sending energies secretly, especially to children who are restless or maybe in some kind of distress, but yours is a great idea. My applauds to you.
Nevertheless, it reminds me of my niece, when she was a little doll. She used to keep awake in the nights and did not let anybody else sleep too. In the cold nights, when everyone would be exhausted pampering her, they would give her on my lap and retire. I would sing some lullaby in vain and then I would try my secret weapon – VK, holding her in my arms. Then within 3-5 mins she would be fast asleep and I would be the hero of the situation by VK’s blessings.
Anyways, its a wonderful experience shared. Thank you.
