Quitting Smoking Tips ?

I hope I can ask this here, if not, I’m sorry! I’d like to quit smoking. I’ve smoked about half a pack a day for 5 years, so I think I’d have a better chance of quitting if I were to cut back first instead of cold turkey quitting. But I’m open to all suggestions. I’m just to the point I don’t want to anymore, because it’s so bad for you and I’m trying to better myself (I just got a gym membership too) and also my son is 3 and keeps picking things up saying “this my cigarette mommy” and now I feel like crap because my son thinks this is okay because I’m doing it! ☹️ and I want to be a better example. So any quitting advice would be helpful! Thank you!
