In brief: 1-2 months of age
Babies begin "practicing" their smiles with primitive grimaces and smirks in the first month of life.
You'll often catch your sweet baby "smiling" in his sleep, which will leave you wanting more. Somewhere b/w 2-3 months you'll notice that your baby is actually smiling "at" you. You smile, he smiles...And so begins the wonderful world of communicating with your baby.

In brief: Usually 6-8 weeks
Reflexive smiling can be seen from 2 weeks on, but first real smiles (in response to your positive verbal or facial expressions) can be expected at 6-8 weeks.
There is some variability for this milestone, but baby's pleasurable, engaging smiles should become easily recognizable by 3 months. It gets even better, as baby's ability to lough out loud (literally lol) appears around 4 months. Enjoy!

In brief: 6-8 weeks
Even newborns will smile during sleep and other times, but a true social smile develops between 6 and 8 weeks.
The social smile (one in response to you talking, smiling, etc to baby) is a very important developmental milestone, so if you don't see it by 2 months, be sure to bring this up at your next doctor visit!
