I gave my baby a day old biscuit (baked yesterday, forgot to wrap up the ones that didn't get eaten, so they're pretty hard) five minutes ago. It's one of those huge "Grands" biscuits, so it's significantly bigger than her mouth. Right now, she's just sort of walking around with it stuck in her mouth, sort of like a big hockey puck. I'm sure she'll figure it out soon enough.
You worry too much about your job. Stop it. You are not paid enough to worry.
