I only tried a bribe one time and that was disasterous and I was afraid that it would set up a future pattern. My son was going to get some blood taken and he was pitching a fit. I told him I would get hima toy and he quieted down and then I apologized to him and told him I was wrong t do that that he needed to get the blood taken and just do it because that was what needed to be done. I would tell your child very quietly and firmly that this is waht needs to be done and approach it with authority. Also put the drops in the corner of the eyes (toward the nose) so that it is not as scarey as coming at his eyeball. T.
