When did your LO start...

Smiling and laughing? DS smiles, but I'm pretty sure it's still just gas, lol. He's almost 7 weeks. So, when did your LO start smiling in response to things (not just gas) and then laughing?

i think close to 3 months

Smiling was around 8 weeks and he just started laughing a few days ago, almost 12 weeks

My nephew is maybe a week or two from three months and his first obvious laugh as a response to something my sister was doing was about 9 weeks she said.

My first started at about 3 months and my second started at about 5 months.

Silas started socially smiling at 6 weeks. His first giggle was at 8 weeks. He started really laughing right before he turned 3 months.
