DS has started to point his finger to our mouths and we then go for a "bite" which makes him laugh. Then he keeps doing it again and again until he's bored.
He's also started to put his finger on our eyes (and nose once) so we respond and say "eyes". This doesn't make him laugh though. He'll then go away and every so often come back and wants to do it again.
Is this sensory seeking behaviour? Am I overthinking this?
