Am I teaching bad habits? Waking and screaming for boob?

My LO (12 weeks) will be out cold for a nap and wake well before her feeding time screaming bloody murder and shaking like a fiend looking for the boob. She literally won’t stop crying or wake up fully no matter what I do. I then give her the boob and she stops and usually falls back asleep. Am I subconsciously teaching her that food is going to make her feel better? This might be ridiculous but I can’t stop thinking she’s just going to be a maniac with food if I continue to use the boob for soothing.
