First baby was 3 weeks, second baby was 5 weeks. Sounds like you got your first toothless grin!! There is nothing sweeter in the whole world. I know most drs say the first smiles are just gas, but that's balony. I don't smile when I fart and neither do my little ones. (well, they might laugh afterwards)

My youngest is now 6 months old and he has the sweetest smile. Take care!
