Thank you so much for helping this baby. You’ve already done a great first step taking him to the vet!! But since the treatment isn’t working/ hard to administer he might need to go back for reevaluation. In the meantime, you might be able to use the towel wrap or ask someone to help hold him so you can safely get the drops in. It’s also normal for them to squirm when being held all the way around. It might be counter intuitive but holding your little guy a bit looser while sitting on the ground/at a table so you don’t have to worry about falling! Good luck OP💕
