Stealing food?

How did yall personally deal with your pups stealing your food? I have a 4 month old and today she stole a whole burger and potato’s wedges off my wife’s plate when she wasn’t looking. Prior she’s broken to plates by hopping on the table or counter to take food off the plates. She’ll even try to take my daughter’s food time to time when she’s in her high chair. I can’t put her into training yet since she’s set to be spayed next week so that takes 2-3 weeks off from being able to hire a trainer.
