So would I just not put any of his information, just my wife's correct?

I could really use some help please. My wife is here and I am filling out the AOS paperwork for her. Her son/k2 will be coming after 6 months. Do I include him on the paperwork for the 864 (Affidavit of Support) or do I wait until he is physically here in the USA? I'm confused on this. where it asks on Part 3, information about the immigrants you are sponsoring. I would just check I am sponsoring the principal immigrant named in Part 2, which would be just her right or would also check the box stating I am sponsoring the following family members who are immigrating more than six months after the principal immigrant? That's the part that confuses me and then listing her son as Family Member 1 with his info? If anyone could help. I'd greatly appreciate it!
