Does you 8 months going to 9 months baby loves biting stuff? My lo bite almost everything. He will put inside his mouth no matter what I give him. He already have 6 teeth and I don't know it is he still going to teething stage again.. it seem like the teething stage nv stop from 4 months till now.. He just don't play with his toys he just bite... n love to bite plastic...

Putting things into their mouths is actually the way that they learn and explore whether something is safe - so it gets really normal even when they're not teething :(

Mine does the same thing so at all times I have to watch him closely he just put cat sand into his mouth earlier today

Get normal. Start to correct the behaviour by saying no. Be firm and consistent.

it is very common. Give him a teether and try to stop him gradually.
