weaning off breastfeeding

Dear mummies Due to health issue i have to wean off breastfeeding earlier than planned. Any suggestion how i can do it gradually as i have a month to do that. Mostof the time im pumping the milk and bottle feed. But i do let babylatch for comfort tomake baby sleep. Should i still pump as per ususl butnot clearthe boobs fully? Or should i just pumpabit when breast is slightly engorged any other tips to avoid engorgement snd mastitis.
