2.5 months old baby - milestones

Ronan is 2.5 months old and is growing well into a cute chubby baby. My elder son Richie was on the thinner side. I used to have lots of difficulties taking care of Richie. Richie used to cry a lot as he used to suffer from colic in the evenings. Maybe being a mother for a second time, it is different. You know how to handle stuff better and can do it easily.

Milestones:
Ronan is trying to recognize faces. He turns in the direction of my voice.
He has started laughing out loudly whenever he is tickled.
He also tries to imitate and laugh whenever someone laughs.
He tries to hold our hand and tell stories.
