Two full years for whoever wishes to complete the nursing. Weaning earlier by mutual consent is permitted, and no blame attaches to it.
Q 2:233
The milk bond
A woman who nurses a child becomes their mother in prohibition — and her husband their father, her children their siblings. Marriage between them is thereafter forbidden for life.
S and Ḥb — five separate satisfying feeds establish it.
Ḥ and M — any amount that reaches the stomach establishes it.
All four require it to occur within the first two years.
Muslim · ṣaḥīḥ — “Suckling prohibits what birth prohibits.”
Keep a record. Where a child is fed by a relative, a friend, or from donated milk, write down who fed them and when. Families have discovered the bond only at the point of marriage, when it was too late to undo.
A father owes the nursing mother her maintenance, whether she is his wife or divorced — Q 65:6.
