My 2months plus baby love to bite and suck on mittens, cries badly if I stop him. What should I do?

I personally wouldn’t stop my baby from sucking if she wants to, so long I am confident the mittens are clean. Babies usually grow out of it as they are exploring their environment including use of sensory and their mouth. Alternatively can offer something else that baby is willing to accept - trial and error. Maybe pacifier?
