Best advice I can give is record everything, but be present.
It may not seem like it but before you know it they go from wanting hugs and kisses to being embarrassed, then they start going out with friends, then its graduation then college.
Becoming a father was the single best thing to ever happen to me. Cherish it and save the memories.
Father's day is especially rough for me without my kids- so I'd also say realize the blessing you have, and try not to take it for granted too often.
Edit- This entire thread flagged and killed, really?
Happy father's day
