I saw this clip yesterday (it's from Oprah) about a woman who has those extra sensory skills (seeing texture/colour when people speak etc).
She has studied babies, starting with her own, and identified 5 separate words/sounds all new babies make at the beginning of crying which helps to tell you what the problem is.
I darn well wish I'd known this when mine were small.
I hope it can help someone out there, and would be interested to know if it does.
