Any ideas?

Hey! My little one is about 3.5mo and seems to be hitting most milestones. Sometimes he appears a little shy. When he wakes from a nap he smiles but then will shyly turn his head then if you make some silly noises he will look at you again and get shy. He makes lots of eye contact on his terms when he’s playing. And if you blow raspberries or stick your tongue out you’re almost guaranteed a smile and he will look quite deeply at your face again before he looks away. But unless you get his attention he would prefer to look elsewhere 😂🙈, especially down and sometimes just gaze at something. He also seems to prefer interaction a bit further away, maybe a foot. When you get all up in his face (except for kisses and tickles) he doesn’t seem to like it. Do I just have a bit of a shy boy on my hands? Is this just an age thing?He definitely seems more interested in other things than people. But he does like people when you really get his attention
