We just noticed that one of our staircase balusters is partially cracked and not aligned like it should be. The orange tape in the picture is just to better indicate the broken baluster.
Here is what the top and bottom look like:
What's the best thing to do here? I have a 3 year old who sometimes grabs onto these as they come down the stairs, and I want it to be safe for him. Watching some youtube videos, I've seen people insert dowel rods in them (but only after they are fully broken). I've seen people fabricate entire new ones (I don't have the skills and time for that). Is it possible to strengthen it without breaking it further? Any resources that might make me a little more comfortable in how these particular ones come in and out, or how I might even try to straighten it?
Edit: Adding picture of nail at the top and the bottom near the Newel post. Nail at top:
