This happens to everyone from time to time. I've been stuck, not really growing at all on YouTube lately.
My advice? Take a look at your content. Is there anything you think you can improve on? Look at your stats, your audience retention. If it's low, whatever views you are getting, aren't staying long.
Just from a quick glance I'm a little confused as to what your channel is about...you have vlogs, songs, a happy wheels montage, some kind of show....? That's a lot of different things in one channel, try to focus on a theme.
Some of your videos have these huge black bars which can turn a lot of viewers away, using " yt:stretch 16:9 " (without quotes of course) as a tag supposedly helps if you have a video that's as black bars.
Also YouTube is all about consistency, and I see you have 2 videos a week ago, and then the ones after are a month ago
how are your viewers supposed to know when a new video is up? Try to set up a schedule.
Best of luck to you and your channel
