Dreams about having a baby can symbolize new beginnings, creativity, or the nurturing of ideas. The fact that you didn't know the gender of the baby might suggest uncertainty or a lack of clarity in some aspect of your life, perhaps related to your relationship or future plans.

The act of your boyfriend putting the baby in a closet next to the cat litter could represent feelings of neglect or concern about how responsibilities are shared in your relationship. The closet might symbolize something hidden or not fully acknowledged, while the cat litter could signify unpleasantness or something you wish to avoid.

This dream may be prompting you to reflect on your feelings about your relationship and any concerns you may have regarding shared responsibilities or communication. It might be beneficial to have an open conversation with your boyfriend about your hopes and worries.
