Is my daughter teething?

Lauren • Had my sweet girl 02/22/20 - 5 weeks early due to rare genetic disorder💗 Had my handsome man 09/30/22 - 3 weeks early due to low birth weight💙

My daughter is 4 months she’s my first baby. I feel her gums. They’re hard but I don’t feel anything that feels like a tooth coming through, but I think she’s teething. Her cheeks are super red the last few days and she’s super sleepy and cranky. She hasn’t even been wanting to get up and eat or play. All she wants to do is snuggle me and sleep. And she had a little tinge of red in her drool.

How do I know if she is?
