Here is my opinion. And it will be harshly against allowing ads. Please don't read if you are going to get upset with me. If that isn't enough warning, I voted for "Yes- Ads are garbage". To put it kindly, ask for donations, not force ads.
If you start a site, don't expect others to pay for it. Make it a pay to access site, or go work for a company who can pay you. Don't go to a street corner and expect money to be put in your hat just because others passing by looked at you and your sitting there singing a song. Even if there are enjoying it and watching you the whole time. Your doing it for free, showing it as free, don't expect cash. The world don't work like that.
A good many people on the internet use ads to make money from crappy content and yet they are rich and I'm sitting poor. How's that fair that you steal my bandwidth for your benefit without my permission and track me at the same time? Screw that. If you want money, make a donate button. People are generous, so you should be too toward others that chose to spend time interacting with your content instead of treating them like a money source like many YouTubers do.
What to do instead of donations? Have a ton of free content and a decent selection of paid content. Do good work, get paid good money. This world might be full of evil, but it also full of good. People will be generous depending on what you have to offer and how you treat them. Also... why are you relying on a site to feed your family? There's always the chance that you won't succeed on the internet (higher chance to fail than succeed. More so if you have ads all over your site. And since ads don't give that much per ad per visitor, you'd have to spam ads especially if you don't have many visitors at all. If you care about your family, don't take a chance on their health, get a job that can actually support them without fail. Don't go spending money on a server that you can't afford... use that money to support your family... and to afford a server, you need money anyway which probably mean you have a job, use it to support your family, use the site for free time killing... common sense people.
