It's totally normal to feel like that. Every mom goes through some kind of fear stage I think. I am pregnant with baby #4 and just as scared as I was 10 years ago with baby #1. Just know that as long as you put your heart into it everything will come so naturally to you once you hold that little baby
Aw girl what you're feeling is normal! I had one technique of getting rid of fear when i was getting close to giving birth the first time: "if billions of mums can do it, sure as hell i can" . And if you're doubting yourself about being a good mom, then you're definitely a great mom. :) all the best for you and your little one, and remember to keep stress away! <3
It will all be ok. Just do what you think is best for you and your baby
