I don't know about you, but several children have died, which should represent your panic and uncertainty about love and marriage. You may break up with your boyfriend.
The meaning of "having children" is that you are completely transformed and a brand-new self. This is the interpretation of dreams and the function of your subconscious mind. Married women also dream of having children, indicating that you are dissatisfied with the status quo and eager to be cared for. It also symbolizes that you have gained a brand-new self and new development opportunities.
