I agree with Tam. We don't know much about Clearbrook's daughter. She might have died at birth, or soon after, like Cheipar. But neither Clearbrook nor One-Eye seemed to display the sense of loss that Moonshade and Strongbow exhibited over Crescent. The birth of Chitter was helping to resolve that grief, although obviously, one daughter can never replace another. Clearbrook has a lot more to offer outside of motherhood, as an individual, and as Treestump's lifemate. Nor could I see Treestump raising a cub while mastering his newfound craft.
