Should she make Grandma stop spoiling her son with junk food?

Grandma watches her grandson on the weekends and when he is with her she spoils him with junk food. His mom Lisa is getting tired of this because it’s gotten to a point where their son is refusing to eat the healthy meals she makes for him during the week and complaining he wants the food Grandma gives him. Lisa wants her husband to talk to his mother about this, but he thinks this is normal for a kid his age and normal for a grandmother to spoil him. What do you think?
