Brad,

You've come a long way in a short amount of time (in your BIAB usage).
Nicely done.

A really good write.
Nice vocal.
Good mix.

Here's a production suggestion (take it or leave it)...
Instead of using only the stick in your drums track,
change to the snare in your 2nd Chorus. Let it run through the Bridge.
The drum drop on Verse 3 is nice. I'd only do that for the first 2 lines.
Bring the stick back for lines 3 and 4
Then back to the snare for the last Chorus and out...

A really nice "Dad Song".
