I feel like this this a dumb question. As if I should already know the answer, but I don't.
I know that babies should not be introduced to foods until 4-6 months of age or later, depending on the resource. Last week we were having dinner with my parents, and my dad said "I wonder what C would do if I let her lick some sweet & sour sauce off of my finger." Of course I gave him the standard incredulous look and said no way! She's only 12 weeks old!
But why? What is the concern? Development of allergies? I'm not talking a spoonful, but a taste. Any insight?
