There is no benefit to the child I wouldn't thought past infancy, there are other ways to bond and stay close to your child, they are are also perfectly equip to ingest their own nutrients.

It's possible that it's the mother pushing it and, if so, then it's potentially a problem. However, it's also possible that it isn't her pushing it, and whilst there aren't any massive positive effects to prolonging breastfeeding beyond around 2 or 3, there ARE some very real negative psychological effects to forcibly weaning a child before they're ready if doing so causes them distress.

As it stands, there's no evidence either way, and stating that it's driven by the mother is a complete guess.
