Is it normal to not be too fond with boyfriend’s son? do i say something?

I (24) have been going out with my boyfriend (25) for almost 3 years. He has a nine year old son whom he had when he was sixteen. The current situation is he stays with his dad primarily, except when he goes to his grandmother on his mom’s side once a week. He sees his mom maybe once a month plus holidays. I for the most part get along with his son, and don’t get me wrong he’s a good kid. There are just some times when I feel like he gets away with too much. Like what kid doesn’t get spoiled? But I believe there needs to be restrictions. And I know it’s not my place to be saying how he should be raised, but that’s where it gets frustrating. I adore my boyfriend and really aspire a future with him. I also definitely want kids, which gets me thinking as to how I would want to raise them. My boyfriend’s son gets almost anything he asks, and when he doesn’t he throws a fit until he does. Shouldn’t we be disciplining him as early as we can? Before he gets even more spoiled as he’s almost approaching teen years. I know I want to tell my boyfriend and express how I feel, but is it not in my place to even say anything at all? Do I just repress my feelings and remind myself that my boyfriend has baggage that neither I nor him can change. I understand that if I choose to be with him, I’m choosing to be with his son as well. How do I stop feeling like this?
