New behavior

Ka

My son is 19 months, his top canines just cut, now we are working on the bottoms. Since Saturday he started acting very irritable, he would scream into his hands and bite them. He’s been doing that since then. Today at daycare he pooped 5 very runny times/was cranky all day and did his hand biting outbursts. Do you think I can attribute this all to teething?

Thank you 🙏🏻
