Write out your melodic lines with rhythm and im sure you will solve your problems yourself.
People just need to experiment, download a notation program and give it a shot. We should encourage people to fish for themselves or they will perpetually take the lazy path and ask others for the answers. I was 6 years old and played around with notation programs (on a C64) if I could do it anyone can and today we have much better programs.
Just because you did this as a 6 yo, doesn’t mean others can as an adult. You are asking him to fish when he can’t put the bait on the hook.

It's all a little strange, the OP can ask a specific question but responses to advice is extremely generic.
