産んだ uses the kanji 産 (production, childbirth) where 生 (life, birth) is also common for the verb うむ. The 産 variant emphasizes the childbirth aspect specifically, while 生む is more general ('to produce, to bring forth'). Both readings are correct; the kanji choice is largely a matter of context and nuance.
