AOS with a B1/B2 Visa

[Matrioshka]

Hello all,
My husband is an American Citizen. We met while he lived outside the states, and now he moved back to the states for a job. I just came to the states with our 3 year old son, to visit him, and now he is asking me to stay and make an AOS.
Anyone has an experience doing that? I dont want to get in trouble but we actually dont want to live separated anymore.
Could you guide me on what papers do i need to submitt. Ive been here only for 15 days.

File I-130 and I-485 (and optionally I-765 for EAD and I-131 for AP) together. Each form has many required materials and other forms. You can search for checklists online.
