Baby refuses help latching?

Cindy
Is anyone else having issues with their baby refusing help when latching? I've noticed that my son is increasingly fussy when it's feeding time. He's obviously hungry, but just fights latching so hard. We've never had trouble with getting him on the breast till now. 
I've noticed however that when I hold him to the breast he searches for the nipple and if I just put it near his face he'll try to find it and finally latch on his own. Anyone else noticing this in their baby?
