The Spit-Up King

I'm sorry that it has been so long since my last update. I have been so busy with Gabe lately. He is awake more, so I spend a lot of my day playing with him. Gabe has a problem. He spits up. I'm not talking the spit up that all babies do after they eat. He spits up a lot and often. It can be two hours after he ate and here it comes. He wakes himself up in the night with spit up that lands on his sheet and gets cold on his face. This does not make for a happy camper. He has projectile spit up. This is so bad that if we are leaving the house, I wait til it is time to walk out the door to dress us both. I carry extra clothes for him and me in the diaper bag. At his one month check-up I asked the doctor about this. We were given a prescription for a dissolvable pill that I give him once a day. The only difference I can see is that we only have projectile spit-up once a day instead of all day. However, he still spits up about an once for every 3 taken in. The doctor also suggested for me to pump and add some cereal to the bottle to thicken it up. This is what has helped the most. Does anyone have any other suggestions to help with preventing frequent spit up?
