im going through that now i feel your pain
my DS1 ped is so beyond booked out its a joke, my daughter couldnt even get an appt! (my first referal for his ped had to be changed as that ped wasnt taking new patients)
finding a dr local who dealt with tounge ties was near impossible and when i finally found one it was a ONE off appt only as his not taking any new patients
now trying to find a new GP and all the good ones are either totally booked out for weeks or not taking new patients

an plus weve got several medical practises that close late at night but stop taking patients from 5pm as they are totally booked out!
