Breast feeding is recommended up to 2 years.
BreastfeedingBreast milk is the natural first food for babies, it provides all the energy and nutrients that the infant needs for the first months of life, and it continues to provide up to half or more of a child's nutritional needs during the second half of the first year, and up to one-third during the second year of life.
World Health Organization, Breastfeeding, 2018.
As the baby grows heavier, the mother's milk becomes insufficient. At year 2 the mother can only provide one third what the baby needs of nutrients, so then it is better to provide other foods.
٢٣٣ وَالْوَالِدَاتُ يُرْضِعْنَ أَوْلَادَهُنَّ حَوْلَيْنِ كَامِلَيْنِ ۖ لِمَنْ أَرَادَ أَنْ يُتِمَّ الرَّضَاعَةَ ۚ وَعَلَى الْمَوْلُودِ لَهُ رِزْقُهُنَّ وَكِسْوَتُهُنَّ بِالْمَعْرُوفِ ۚ لَا تُكَلَّفُ نَفْسٌ إِلَّا وُسْعَهَا ۚ لَا تُضَارَّ وَالِدَةٌ بِوَلَدِهَا وَلَا مَوْلُودٌ لَهُ بِوَلَدِهِ ۚ وَعَلَى الْوَارِثِ مِثْلُ ذَٰلِكَ ۗ فَإِنْ أَرَادَا فِصَالًا عَنْ تَرَاضٍ مِنْهُمَا وَتَشَاوُرٍ فَلَا جُنَاحَ عَلَيْهِمَا ۗ وَإِنْ أَرَدْتُمْ أَنْ تَسْتَرْضِعُوا أَوْلَادَكُمْ فَلَا جُنَاحَ عَلَيْكُمْ إِذَا سَلَّمْتُمْ مَا آتَيْتُمْ بِالْمَعْرُوفِ ۗ وَاتَّقُوا اللَّهَ وَاعْلَمُوا أَنَّ اللَّهَ بِمَا تَعْمَلُونَ بَصِيرٌ
Breastfeeding is limited to two years in the Quran.
How could an illiterate man who lived 1400 years ago have known how long to breastfeed?
Another less known benefit of breastfeeding is the bond between the mother and the baby.
Is Breast Milk the Key to Mother-Baby Bonding?The secret to mother-baby bonding might be breast milk, according to new research that determines that breast-feeding mothers are more likely than formula-feeding moms to bond with their infants in the months after they are born. They also demonstrate stronger brain responses when they hear their baby cry, according to a study published in the May issue of the Journal of Child Psychology and Psychiatry...While participants lay in a scanner and listened to clips of their own baby and an unknown child crying, researchers tracked what areas of their brains lit up. All mother's brains were more active when listening to their own babys cry, but the changes in the breast-feeding mothers relevant brain regions were far more significant.
Breastfeeding is key to mother-baby bonding; a very powerful social bond. This was known recently, however this was portrayed in the Quran 1400 years before it was discovered. On the final Hour this very powerful social bond breaks.
٢ يَوْمَ تَرَوْنَهَا تَذْهَلُ كُلُّ مُرْضِعَةٍ عَمَّا أَرْضَعَتْ وَتَضَعُ كُلُّ ذَاتِ حَمْلٍ حَمْلَهَا وَتَرَى النَّاسَ سُكَارَىٰ وَمَا هُمْ بِسُكَارَىٰ وَلَٰكِنَّ عَذَابَ اللَّهِ شَدِيدٌ
"Every nursing mother will discard her infant" today we know that this is the most powerful social bond.
How could an illiterate man who lived 1400 years ago have known that breastfeeding bonds the mother with the baby?
The Quran (Koran, the book of Islam) contains scientific knowledge that could not have been known 1400 years ago. It ranges from basic arithmetics to the most advanced topics in astrophysics. You are invited to go through those miracles and judge for yourself.
