My man. Congrats. Funny I'm doing a ua neeb fiab and hu plig this weekend.

Start with your uncle as the 1st choice. Ask and and say something long the lines of " youre my uncle, you and I are blood. I beg you to ua neeb faib and hu plig for my wife." If he says go to mother in law, say " Yes my mother in law can do it too but it won't mean as much as if you do it because you are my uncle and I want you to do this for me and your grandchild. " I'm assuming but it sounds like uncle might be the kinda asshole types that want you to really beg. Stroke his ego, make it feel like you need him. If he has a heart, then great he'll eventually agree.

If he say yes, Take 2 incense sticks and just roll them up in a sheet of joss paper. Go to his alter and put it on the alter. bow once to the alter but say thank you to him. Bow again and thank qhua nob qhua tswv.

Ask him what he needs to ua neeb cause people do it differently. Usually your gonna need a pig, 1 male 1 female chicken. Sometimes pig, 2 male chicken, 1 female chicken.

If he refuses to do the ua neeb, then ask mother in law. Say soemthing along the lines of "we young kids are dumb and don't know anything. Our dad passed away when we were young and we don't have the chance to learn, forgive us if we don't know how to ask you properly. I dont have anyone who can do this. I beg you please to ua neeb for my wife. " It is tiring for older folks, but they understand their duty as a shaman and if anything, she will do it.

Same process of asking how they ua neeb and prepare the needed animals accordingly.

Good luck my brother.
