Thank you everyone for the recommendations and concern *hugs*.

I'll try the foods suggested one at a time.
FL he had far less banana than that! :/ weird.
The pharmacist also recommended prune juice diluted with water so might try that first.
The doc prescribed some stool softener medicine and anti inflammatory ointment both of which I administered earlier. He did do a better poo before the meds so hopefully he's on the way to recovery.

Dates aid digestion? I didn't know that! However we've only been getting date filled sweets at people's houses (ma'moul) so will have to see if we have dates left over from Ramadan at home.
