Your bubba sounds very similar to mine over the past couple of days...and I also have other children to worry about....hopefully it is just cause of a growth spurt or something. My little one has mild reflux and I found elevating the head end of his mattress a great help. They also suggest keeping them upright for 20mins after a feed, but realistically who has time for this?? They say coloxyl drops are the best thing for no 2's, so I'd continue with these and if in doubt go to a dr (if only for reassurance)
