Sister, dreams can have different meanings, and only Allah knows their true reality. In general, seeing a healthy baby in a dream is often understood as a sign of blessing, happiness, new beginnings, or a responsibility that brings goodness. Feeding and caring for the baby may reflect your nurturing nature or a blessing that Allah may bring into your life.
Since you are not married, this dream does not necessarily mean that you will soon have a child. If the dream left you feeling peaceful and happy, then think well of Allah and hope for goodness. The Prophet ﷺ taught that good dreams are from Allah, so thank Him and make dua for goodness.
May Allah make this dream a source of goodness and barakah for you, grant you a righteous spouse, bless your future with happiness and peace, and give you what is best in this world and the next. Ameen 🤲
And Allah knows best.
