Greedy baby FTM

Hi guys I’m a first time mom, just for future reference just in case I sound dumb 😂. But my daughter (9 mo. old) is so greedy to the point where I can only eat if she’s eating. If I don’t share my food, she crys like I’m abusing her. I try to ignore it sometimes because I don’t want it to become a bigger habit. but she’ll legit cry until you give her some. She even cry’s when she sees strangers eating outside, she wants anybody food 😭. Is this normal?? How can I stop this??
