How much?

This is day three for me postpartum in the hospital. I can only get a few tiny drops of colostrum out per day. It doesn't seem to be increasing. My stay in the hospital has been stressful and every time I sit down to try to pump and stimulate I get interrupted by a housekeeper, tech, nurse and have to stop and let them take vitals or something else then by the time I can settle back down, the baby is screeming and i gave to supplement with formula. I'm afraid due to this my milk supply will never come in. I'm a ftm. Anyone have experience or advice with getting milk inane getting past the colostrum stage.
