Is it normal for someone to get comfortable too soon in a relationship?

My new official bf and I have been dating for 10 months and recently we decided to try the label thing. But we have been acting like a couple for like the past 4 months. So my problems with him have put me to question how he feels about me. However, I recently looked back to when we first started going out, and he wasn't like the way he is now. All the things I wish he would do he has done in the beginning. But who I am dealing with now is who he really is. So I feel like he has gotten already comfortable with me that he thinks he doesn't have to do much to make me feel good. I dont think its because his feelings have faded for me or else he wouldve broken it off instead of officially committing to me. I think about "I wish he can do this, I wish he can do that" and I forgot that he has done those things but like the first 3 months of us dating. He would take me out to dinner enthusiastically, he asked how I was doing, he would let me talk to his parents on the phone, he would console me when I was down, etc. I once went to the hospital and he asked if everything was okay. Recently, I told him Ive been going to the doctor for so and so and he hasnt asked how Im doing. I feel like now he got comfortable and settled that he thinks he can 100% be himself and doesn't have to do those things anymore. Of course I love that he feels he can be himself but that doesn't mean he can't put a little effort like he did before. Its like okay we're in it for the long-run so why bother putting more effort. Like I said its only been like 10 months and we just made it official, the honeymoon phase is just beginning. Is it possible that he has gotten comfortable which is why he doesn't put enough effort like before? Which in a way I should take it as a good thing so I should just confront him on what I want from him?
