Okay, first thing...This is completely normal! It is natural to feel like you're going to fail at parenthood as your first baby's birth gets closer. However, post partum depression is something that happens surprisingly often. But there's no need to get too worried about it. They have medication for it, as well as support centres and groups you can go to.
I'm sure that when you have the baby in your arms, all your worries will vanish for the time being. So just sit back and relax, and enjoy counting down to ethan daniel's birthday! Everything will be fine. :)
