Help! My baby yells at me!

She’s 11’months old and a very good baby. Lately though, she’s been yelling at me a lot. If she doesn’t get food immediately, she yells. If I’m feeding her something she doesn’t want that minute, she yells, so I make her something else. This isn’t a cry, she actually yells at me. I’m worried about two things. A) i don’t want her to be a yeller. We never yell at home, and I don’t want her to have this negative attitude. B) I don’t want her to get used to mommy making her special meals when she doesn’t want what’s on the table. At the same time, I need her to eat. What to do? Any advice? Is this a phase?
