Ok...have a 4 week old boy...had been doing ok...rough at first but getting better. He is gaining weight well and has good output with the diapers. The past few nights he has been spitting up after every feeding...not right away but as long as 2 hours later? He will gag, spit up a little....sometimes it doesn't come out...he just gags and coughs. Many times while he is feeding he will grimace and kind of twist his head while still latched on...OUCH! Sometimes he clamps down hard on my nipple...double ouch. We were awake lots last night trying to control the spit up/gagging thing. He is sleeping in our bed btw....thoughts/help? Thanks!!!
