6 weeks too soon?

Jasmine • Mommy of two precious angels and Sebastian Tobias Brownlee

My husband will be deploying before my 8 week appointment to hear the heartbeat. I looked it up and it said the earliest you can hear it is 6 weeks. I was wondering if that was true? Has anyone else heard their baby’s heart at 6 weeks? If it is true then he will be able to be there for that one.
