Scared

So my little bundle of joy is turning 2 in may. I love him to pieces but to be honest he's a handful. My husband and I are deciding on if we should have another baby. I would like to do so soon so they are not too far apart in age. But I did have a problem with pp depression after my first. I really don't want to feel like that again. Although I know it goes away. What to do? Thoughts
