I feel like some days I'm mature and then I get sad because some days I feel like I'm so immature and won't be able to raise children.

My husband and I are ready to start out family but I have these horrible doubts I cant do it. My husband says I'll be okay and we'll learn together (he's in 30s). But I worry because I'll be the one home with the baby everyday and bring baby here and there for appointments etc. He also says I'll grow once we get pregnant and ill learn more throught out the pregnancy. I just need some encouragement ladies. I don't know what to do. I'm 23.

I'm ready for kids and I'm really great with them but I just have these doubts.
