Have you called your doctor?Maybe there is something he can give you to treat the blister that wouldnt harm the baby.My 16 month old sucks his thumb,I tried giving him a paci too but it doesnt work.However my child ONLY sucks his thumb while falling asleep in his crib,then he takes it out and sleeps the rest of the night without it,he doesnt even walk around with it in his mouth unless he's ready for a nap.My first loved a paci,and this one likes his thumb so I have had it both ways.But he has never gotten a blister.I say just call the doctor and ask them what's the best method,I'm sure your not the first one to have this problem.Heck while I was taking my baby once to his appt. a guy who had brought his son in actually grab the doctors prescription pad he left on the counter for a min and ran out the back door,naturally he was caught.But it was def a first for my doctor and he told me that they see alot of things you wouldnt expect everyday.
