No — the text names no children before Cain and Abel. Genesis 4 introduces them as the first sons of Adam and Eve, full stop. Eve names Cain with what reads as a firstborn cry, "I have gotten a man from the LORD" — striking because the ground's curse had just fallen and death had just entered the world.
The "sons and daughters" many readers expect comes later, in Genesis 5:3-4, after Seth is born at Adam's age 130. And Eve's own words at Seth's birth close the door any sooner:
So two pieces of evidence settle it: Cain and Abel appear first in the story with no earlier siblings named, and Eve treats Seth as Abel's replacement, not as a younger brother coming after a long line of unnamed firstborns.
One knock-on is worth naming: Genesis 4:17 has Cain taking a wife and building a city — which only works if Adam and Eve had other children (almost certainly daughters, or nieces through any sons born between Abel's murder and Seth's birth) that the chronicler didn't bother to list. The biblical text is genuinely silent on those siblings; what we know is they must exist for the rest of the story to hold.
