Dreaming of giving birth can represent a few things. It can be a new break through in your life that you have been emotionally and mentally preparing for, relating to new concepts or beliefs you are taking in. It can also be relating to anything new in your life that has new responsibilities . Such as a new business. It can also relate to your spiritual gifting and taking care of those new gifts. With it being small, is reflecting what it relates to in your life, you gave birth to it, and it came out small. Meaning what you recently have given birth to is "small" spiritually.
