Is it permissible to slaughter more than an `Aqiqah and in several times for the same baby?

Q: I have been granted a newborn male baby; by the completion of forty days since its birth, I slaughtered an `Aqiqah (sacrifice for a newborn) of one sheep. After the passing of ten days, I slaughtered the second 'Aqiqah of a goat. Since the first `Aqiqah belongs to the sheep species and the second one to the goat species, and each one of them was slaughtered separately after some days and the matter is as I have mentioned, I hope you will give me a Fatwa of whether these two `Aqiqahs meet the same conditions for `Aqiqah. May Allah cherish and protect you! (Part No. 10; Page No. 448

If the goat was one year old, it has met the same conditions for an `Aqiqah. With regard to the newborn baby mentioned above, offering one sheep and one goat is enough.May Allah grant us success. May peace and blessings be upon our Prophet Muhammad, his family, and Companions.
