hi dear... babies mouth nein cheezein daalenge. Yeh humare upar hai ki maximum cheezein avoid kararye... khane ke alawa koi bhi aur cheez pet mein jaye, yeh acha nahi hoga... so its better to avoid it...

While labels will not mention toxicity, I'd suggest these shouldn't be put inside the mouth anyways since baby is too small and could even choke.
