My 11 year old son takes a lot of different medicine each day. He can’t swallow a pill yet, so we crush it and put it in grape juice for him. Would he be allowed to take it with grape juice during the 9 days?
If there is no other solution, it is allowed, since it is necessary for medical purposes.
All the best
