When did your baby start smiling at you on purpose?
Our son is 6 weeks old and sometimes when I talk to him he gets these little expressions that almost look like smiles but I can't tell if it's real or just gas. My mom keeps saying he's too young to actually smile but then I see videos online of babies smiling at like 5 weeks. At what point did you guys know your baby was actually reacting to you? It's the one thing keeping me sane during the 3am feeding sessions.
The social smile usually hits around 6-8 weeks consistently. It sounds like you might be catching the early ones - that little expression when they're processing your face. It gets way more obvious and frequent pretty soon.
