Doesn’t stay latched

Ni

My baby doesn’t stay latched, it’s like he doesn’t like my nipples or something. He gets so mad and screams!! He’s 2 weeks old.

I started pumping into bottles to feed him that way but I noticed I can’t keep up with his feedings. I pump every 2 hours, 2oz total. He always seems so hungry and unsatisfied:( any ways how I can increase my milk supply?? I’m really taking it hard over here 😥
