I need help. Daughter busted head open! 😬

Tiffany • Christian. Mother of 3. 3 living and 1 angel. 10 years together married 7.

My daughter and my son were playing ( running in house) and my daughter tripped. She busted her head open. We contacted my grandmothers nurse and she said the gash was ok and no stitches needed. A few hours later after we uncovered it and the bleeding has stopped it has seem to get wider/ deeper and worried she does need stitches. Any help? First pic is when it happened. Second pic is a few hours later.
