Why does my baby only cry and act up when I’m around?

He probably feels most comfortable expressing his feelings with you and/or sees you as the one to turn to when he needs something. This is totally normal and shows your baby knows he can count on you for comfort and needs :)

My bd says that, que lo tengo chiflado but he says it as if it’s a bad thing.

This is completely healthy, normal, typical behaviour.

I could’ve honestly wrote this myself!🤣 just been told that he feels the most comfortable with me and able to express every emotion as I’m his comfort🫶🏻

Because he feels safe to express himself ❤️

Bc baby’s know who will put up with their shit 😂

Feels comfortable and safe. Everyone always tell me how good my boy is but as they say that im looking at his face all serious and nervous like he just doesn't feel comfortable so as soon as I'm near he can be himself

That’s the way your baby communicates with you. And knows that he or she will get their way cause you’ve probably shown patterns that he always will.
May I suggest sign language to him to help ease the crying. If he is thirsty, hungry, hot, cold, dirty (diaper change), his favorite snack… I taught my baby to voice and sign all these simple words so that I can better communicate with him. Good luck!
