Solids?

So our baby girl is 5 months and a week old. We just gave her oatmeal for the first time ever today lmao. She hated it 😂 I read somewhere to be persistent so we’ll try again tomorrow. I guess it can take babies a little bit to be like ok this is different but fine. Those of you who have started solids, how did your babies take it? Any tips? We have the other first foods but wanna wait until she gets a hang of the oatmeal and eating off a spoon to feed her those. First time mom so would love any and all advice.
