In the situation you describe there is room to permit resuming breastfeeding.

If there is a reason that a child over the age of 2 but under the age of 4/5 didn't nurse for three days (e.g., the mother was away, illness, or, as in this case, an attempt at weaning), and it is in the child's best interest to resume nursing (whether for health reasons or an emotional need), it would be permitted.

Please feel free to get back to us with any further questions.
