Cassie • 26- Married - 2 sons 🥰 - Baby #3 on its way!

My daughter is 3.weeks and was born 4 weeks premature but needed.no nicu time. Her heart rate on her owlet says its basically in 160s even in the 170s some never in the.140s or lower. At her app they made me hold her until her heart rate lowered and said it was ok. She has a app in a week think this is somthing that needs addressed? Or is it.normal
