Extremely stubborn and suspicious

The Bumble prefers to eat off of my or Mike's plate. When I fix her her own plate of food, she regards it suspiciously. I don't know why, she's always eaten exactly the same thing as us. We totally skipped jarred baby food, so if you ask me, we have done nothing to earn her distrust. But now she's asking me to take a bite first before she agrees to eat anything I make for her, even if it is off my own plate. I think she thinks we are trying to poison her, perhaps so that we can finally get a decent night's sleep. Rest assured, little Bumble. If we find a sleeping potion, it's going in your sippy cup.
