aqeeqah

my husband is 31years old , and upon inquiring from my mother in law , we have found out that he has nt had a aqeeqah, because his parents didnt know about deeni matters. can it still be done ? is there harm in not doing aqeeqah? because he is always ill , would it help to sacrifice animal can someone organise aqeeqah for themself? what should be done to rectify the situation? should you give qurbani or sadaqah instead? please answr as soon as possible.
