Father questions paternity

Valeria

So when I gave birth my son came out very light skin and his father is dark. He right away says he isn’t sure due to that. The tips of my sons ears are darker than me but lighter than him. My first son came out light and got as dark as me over time. So what do you think. I think he looks a lot like him. I told him if you want do the test I rather know than to you to hide it from me. Her are some pics

Him with his sister. From my first husband.

I made this a day after birth.

Everyone says he looks like him but he still questions it. 🤷🏻‍♀️
