I wouldn't say it has to be laid to rest, but it has to be put on hibernation right now.
Your family is young, and this is the point in your life where you need to treasure the moments with them. Watch your kid grow up, enjoy time with your wife.
Once the kid hits his teens, you will find yourself with more time to continue your comic endeavours. He will have other priorities in life, and will have enjoyed with childhood with quality time with his daddy.
Keep on practising, though. Draw a page here and there when you feel the urge, just to not get rusty, write down the story you want to tell, revise it, save it.
In ten years time you will have the time and most likely motivation to go back to it at full pace.
And good luck with your mugen endeavours too.
