I empathize with your concerns. In my experience, a non-custodial parent who does not take advantage of current orders to parent his or her child(ren) is almost certainly not going to receive new orders that will increase his or her parenting time.
I'm not sure why your attorney is affirmatively trying to modify the custody orders so as to make them more restrictive. My preference is to, "let sleeping dogs lie," because the longer the status quo remains, the less likely the court will grant a modification.
So, that's something that you may want to discuss with your lawyer -- because I'm sure that he or she has a rationale to support the show cause hearing at this time.
