With the ideas and posts you'd made I would imagine just a "Welcome Home Baby" and you waiting for him should make him feel like the luckiest guy on Earth. Touching home and seeing the love of his life will be the most rewarding part of his return I guarantee. Anything else is just extra jelly on the sandwich.
