What is the ruling on a woman who weaned her infant at one and a half years old, then remembered after five days that her deceased husband had intended for them to breastfeed for two full years? Should she resume breastfeeding or continue with weaning?

It is permissible to wean a baby before two years of age if it does not harm the child and both parents agree to it. Otherwise, neither parent may make this decision independently. If one of the parents refuses weaning, the child must be breastfed for two full years. It is a condition for the permissibility of weaning before two years that it does not harm the child, even if both parents agree.
