Each day one new benefit breast milk for babies. One of the facts found that knowledge about breast milk is that breastfeeding a baby for two years after birth is really very useful. (Rex D. Russell, Design in infant Nutrition, http:// www. Icr.org/pubs/imp-259.htm)
God tells us this important information about 14 centuries ago, the only known through science recently, in his verse "....split them (babies) in two years ...".
"And We have stressed on man concerning his parents, his mother bore him undergoing weakness upon weakness and his weaning takes two years that give thanks to Me and to your parrent. Lastly, the return is towards to Me" (Quran, 31:14).
Those are miracle of Quran.
