Oops I Did it Again...

My poor son. He woke up starving. I fixed him a bottle and began feeding. I noticed he was gulping, literally gulping down the formula. I thought dude okay, relax. He drank about 4 ounces in 5 minutes. Burped so loud he scared himself. And then I realized I had a bigger size nipple on the bottle. He is actually trying to catch his breath right now. This is the second time this happened to him.
