Is it possible for a baby to be teething at 3 months? Son drools like a leaking faucet. Chews and sucks on his hands, fingers, and chews on a pacifier instead of sucking it.

He’s been cluster-feeding for the passed 2 days. Burped each time. Spits up here and there, not always.

Anything will help, thank you!
