tiktok certainly seems to prefer if you post a draft using api and then manually publish it using the tiktok app on your phone, but the other platforms like youtube, instagram and facebook don't seem to mind. Its also recommended that you warm up an account manually before posting to it using an api. I've recently built and agent first social media scheduling tool: https://mallary.ai
setting up the developer account is easy, but getting approval from each platform is quite tedious! I've recently been thru it with my social media scheduling tool (mallary.ai), did you get approval from all the platforms yet?
I made a free product out of one of the use cases for YesNotice "Get notified when a new movie or TV show is released". It's here: https://www.premierepal.com/
Give the kids a break... let them be free to play. They are only 7 and 10, why do they need daily routines, task completion, accountability, timers? Sheesh.
