I raised my concerns in other topic that I have a boy born in 38+3, overall healthy and achieved all milestones for 2 months, but not smiling socially.
When I talk to him he is staring at my eyes and face, making grimaces, making O with mouth and moving arms and legs happily. I also notice happiness on his face, but still we did not get real ear-to-ear smile.
The max we got is like in this video:

Is this acceptable social smile for 2 months old baby to consider that social smile milestone is achieved?
Is there anyone else who did not get social smile by 8 weeks?
