She held the child to her chest.
Literal
She [topic-は] that child [object-を] chest [target-に] embraced.
抱く ('to embrace, hold in arms') is the basic verb for cradling or holding someone — often a baby or child — in one's arms. 胸に marks the target of the embrace, against the chest. The verb gives a calm, tender feel; the more emphatic compound 抱きしめる ('embrace tightly,' fusing 抱く + 締める 'tighten') would convey a fiercer or more desperate grip rather than this quiet hold.
