Congrats on your sweet new baby Brady! Really it's making me wish I had a baby too. (Kaji's 2 yrs old already) He's just too cute. I think I have puppy envy!
If you're open to suggestions, have you considered a break away collar for his ID tags? That's what I use with my little stinker. It holds on pretty well, but when he gets into mischief and gets his collar stuck on something, it just falls off and he's safe.
