I actually took a break from YouTube for 3 years and just returned to it a few weeks ago. In preparation for returning I actually made some content in advance, I think it was roughly 4 videos. I found that this actually helped ease me back in to it because I then didn't feel the need to find time to rush content out, and if I did struggle with time then i've got content to cover me for a while. I've found this to be working for me so far.
One other thing is it may come down to what schedule you want for your channel. If you are trying to get back into content making but are very busy in other areas it's worth looking at how often you want to publish content. You may have already decided that, but it's worth starting small, then if things are going well increase the schedule to where you want it to be.
