Guidance releasing new hit children's songs

I believe I have a few new children’s songs I think will be extremely popular at the moment.
I don’t have anyone to advise me.
I uploaded the songs to Distrokid, ready to launch in a couple of days.
But, I don’t want to make the wrong choices eg include in Spotify or not.
How can I find the right category of person to help me launch in the best way?
I’ve put a ton of work behind the creation of these songs, now it’s time to put them out in the world and I cannot afford to do it wrong.
(I’m an unemployed single mother with good ideas.)
Good advice would be tremendously appreciated.
Also, should I be asking this somewhere else?
Thanks in advance!
