Hello Cassandra, my name is Daniela. I don't have too much experience since I only have one baby, but if I can give you a humble opinion and encouragement, I would have to say that I think it is completely normal to feel scared. Nonetheless...It seems to me, from what you share, that you have been very well prepared in the past and have an excellent record of good deliveries, so you shouldn't worry too much :)

Now, by being alone, do you mean just not being with your husband when labour begins? I'm sure you most have some other support person that can come to you faster when the time comes, like a doula, relative or close friend. If not, you may want to consider enlisting a few people in your speed dial that will be available.

I'm sure you will be ok and I wish you all the best with your 3rd baby!

Bye, Daniela
