You're his daughter, 3 years old. Your mother has abonded you because she thought she can't look at you. So, he's looking at you from now on.

You were crying because you want Mattheo to cuddle, but he gently forces you down on your crib because he doesn't want you to get used to being so clingy.

As he noticed you're crying louder and searching for him, he says "Shh...", and then lays down on your crib. He leans your head down on his chest.
