You could get away with submitting a lot less, and bringing the rest to your interview. For example, you could probably just submit the tax returns and CBRA of your child with the application, those are the strongest pieces of evidence anyway (compared to something like airplane tickets or utility bills).
Depending on the state you were granted a divorce in, you could also probably get a copy of the divorce "certificate" (e.g. Virginia provides one) from the state's vital records office and submit that instead of the full divorce decree. Certificates are one-page documents that prove a divorce occurred. Decrees are typically several pages that have a lot of unnecessary details.
Shorter the application, the better it is for whoever reviews it.
