Excited but scared

Paige • 18 years old. First time mommy! 💙11-11-16💙
Throughout my entire pregnancy I've been beyond excited and happy about having a baby and wishing time would go by faster. Now that I have roughly about 3 months left until my baby boy is due, I'm terrified. I'm not afraid of the labor pain, it's more of fears that something will go wrong during labor or that someone will kidnap him (caused by a nightmare I have frequently) or that I won't be able to care for him the way he needs to be cared for. I've talked to my boyfriend about it and he's constantly reassuring me that everything will be just fine but I still find myself worrying about a lot of things. Are there any other moms here that have the same worries that I do? If you do, how do you cope with it?
