Seizures or reflux

My baby is six weeks old today. Saturday night he started doing this weird seizing up thing. His face would go completely red, stopped breathing, fists balled up and legs pulled in. He did it three times that night and another the next morning. We are currently in the hospital since Sunday morning with no signs of being released. My poor baby. I cried the whole time they we doing tests. They

did a Ct scan, spinal tap, catheter, blood work, upper gi series. Waiting on results for the upper gi and then they will order an eeg. I feel like I failed him. Have a second cousin with epilepsy. Praying for answers.
