I took some encouraging phrases along for my birth as well but I didn't look at them more than a few times. What was helpful was that I meditated on them a lot before going into labor...so they came to my mind throughout the day. A lot of them are from a Christian perspective so forgive me if that's not what you're hoping for. Good luck.
Here's a few:
“... babies know how to be born.”
“... you only hear about the bad stories. “
‘Cast your anxieties on Him…’
‘I will never leave you…’
‘Is anything too difficult for the Lord…’
‘Do not be afraid….’
‘Do I bring to the moment of birth and not give delivery…’
‘For God did not give us a spirit of fear, but a spirit of power and love…’
‘ I am He who will sustain you…’
‘I wil strengthen you and help you…’
“Be strong and courageous. Do not be afraid or terrified…for the Lord your God goes with you; he will never leave you or forsake you.” -- Deut 31:6
“So do not fear, for I am with you; do not be dismayed for I am your God. I will strengthen you and help you; I will uphold you with my righteous hand.” -- Isa 41:10
“Listen to me…you whom I have upheld since you were conceived, and have carried since your birth. Even to your old age and gray hairs I am he, I am he who will sustain you. I have made you and I will carry you. I will sustain you and I will rescue you. “ -- Isa 46:3
He would not call you to something and then not give you what you need!
This is worth it! Your little one is almost here!
Your body is made for this!
The Creator is not a careless mechanic!
Focus on power not pain!
You’re going to get huge! There is room for the baby to come out!
God is in control!!!!
“Birth is only as risky as life and death. “
Labor pain is purposeful and temporary.
