These are the requirements for a qualifying child, but they forget to post the qualifications for qualifying relative. 1. Not a Qualifying Child, 2. Relationship (your children qualify), 3. Gross Income (Less than $4,050), 4. Support (You provide more than half their support). The only thing I can see here disqualifying you is the support test. Do the amounts that the church provides to your child qualify as support? If they do then you do not meet the tests. I personally think they do since you take the amounts paid as a charitable contribution. There was a court case in 1990 Davis vs. United States where they got in trouble for claiming they were both supporting their child and also giving to charity with the same dollars.
And so it is not a big surprise when the LDS church changed the missionary age to start at 18, instead of 19. Too bad for daughters though who start at 19.
