Is 6 weeks early for a first word?

My baby has been saying "Hello" and "Yes" on her own. Not once like it slipped out and sounded similar... shes constantly saying those words. She did it to our midwife and our health visitor and they were shocked and said it was really early but apparently i was that early too.

I'm just really happy I can hear my baby speaking really clearly and she says it all the time (mainly hello) 😍 i guess it'll get annoying soon enough 😉 haha i'm just inlove with her
