So choke instead of scream? Not a great choice. Eating some thing chewy will work. When my children were small, before they were eating solid food, they were nursing. When we flew anywhere I made a point of nursing when the plane took off and landed. The sucking motion keeps their ears in good shape.

I was on a flight from hell with a family in front of me, their 2-year-old in agony. He already had tubes in his ears for infections, and that wasn't enough, he screamed for probably 30-45 minutes after the plane took off. His ears eventually evened out, and the screaming had tired him out so much he slept, but then we had to land. . .
