I had to bite my tongue a little while ago when I saw a woman on the bus pre-chewing crisps for her baby. I'm talking putting a crisp in her mouth, chewing it up, getting the mush on her finger & then putting her finger in her babies mouth.
I'm not being funny, but regardless of age (I'm unsure how old this baby was 6/7 months maybe) if your baby can't chew something, don't give it to them! Wait until they can.
Also, the sight was fairly disgusting too.
I have to bite my tongue with people that wind children up then laugh at them. My family do it to my LO & I don't keep my mouth shut with them. Like, taking his dummy out & laughing when he cries. It's sick. I hate it.
