Narrative:

While passengers were boarding passenger X assigned to seat XX3 did not have a mask on. The gate agent had not briefed the flight attendants on any exemptions; so I looked on efb and just saw an infant in XX3. I asked the forward flight attendant to ask the gate agent who was standing in the galley if we had any late exemptions and he advised no. Gate agent came to back of plane to talk to passenger X and advised him he would have to wear a mask since there was not an exemption. Passenger X advised he had gotten an exemption in ZZZ1 on way to ZZZ and showed a boarding pass that in ink was written exemption from mask but we had no idea who wrote it. Passenger X then pulled out a letter that only stated he was disabled and that he gets paid a certain amount. Gate agent was advising it was ok with him for passenger X to go; but I said no we need to talk to the captain in regards to this. We went to the captain who made a phone call and was told passenger would need to get an exemption for our flight. The gate agent at that time went to gate to meet a supervisor and see if anything was in the record. When he came back suddenly there was a record for the passenger with the exemption of taking mask off for xx minute intervals. I then looked at my efb and now it showed a wheelchair where the infant had been and the infant moved to XX4. We closed up after advising passenger X of the exemption and the xx minutes only. During the 2 hour 30 minute flight we had to tell passenger X at least 4 times that he had to put mask on and when he did we had to tell him over his nose and mouth not just his chin. Passenger also had a very disruptive 2 yr old as well; that was coughing and sneezing and passenger X advised us his children gave him high anxiety and that was why he could not wear mask.passenger X's total disregard of mask rule and even though he got [an] exemption to take mask off for xx minute intervals he did not follow the exemption.
