Ok so I've been with my SO for a little over a year and after a couple of months I set into motion a plan to get him to discipline his son (5yrs old). He has put forth some effort and has done a little better but, the problem is that he won't be consistent. This child is so smart and can be an absolute joy to be around when he knows he can't get away with anything. I know part of my SO's problem with discipline is that for one he lost another child at 6 weeks old and he feels like he needs to give this one the world.
