My dd would bring her knees up to her chest and cry if I put her down on her back and she still had wind to get rid of. Winding for an hour seems quite excessive, especially at that hour of the morning! Try putting ds down on his back and see if he brings his knees up. Also another little tell-tail sign of wind is a slight blue shadow between their top lip and nose.
I found the best ways to get dd's wind out was either: have her facing with her head on my shoulder, pull her legs down so her body is straight and pat her back while jigging slightly up and down. Also, have her sit on my knee with right hand across her chest, thumb and little finger under her armpits... pat her on her back while jiggling my knee (gently).
As a preventative measure you should try burping intermitantly during your feeding i.e. in between breasts.
Good luck
