Can i move my kittens now?

my cat had kittens 3 weeks ago today. they are crawling around and most of them have actually crawled to me, and they are all familiar and comfortable with me now. the problem is, they are under my bed. 2 of them have eye infections that the vet gave me ointment for today and it is really difficult to get them form under the bed (its against a wall on one side of it) i was thinking of moving them to another area so that it would be easier for me to give them the medicine. is this ok? if so, what can i do to make the mom feel that its a safe area? and if i shouldnt move it would it be ok moving the bed back and forth? i am trying not to stress them out more than necessary. thanks for any help!
