When this happened to me with my baby his doctor gave us saline. I put a few drops in his nose and used the suction to relieve any congestion he had after choking. This helped with his spit ups and they went away within a day or so. As for the fast let down, I usually do the side lying position to help slow it down. But I’m sure they unrelated! But always trust your mom gut and keep an eye on him
I have a fast let down and my boy often coughs and splutters on it. Apparently leaning back while they feed can slow it a bit. Unfortunately my son wont feed like that anymore xxx
