8 month old refusing bottle??

Hey guys! I’m a ftm (with another on the way hehe) but I was just wondering if any of you have had the same problem? My son is 8 months and since he’s been introduced to solids, he’s been refusing his bottle more....is there anything I can do or replace it with? Or do I just make sure he has his 3 meals + water?? I have no idea what to do and my mom doesn’t know either since she didn’t have this problem 😅 any help or advice is appreciated! (He’s a preemie btw!)
