Jacob spits up a fair amount of milk always, started around the same time as your little one and he still does, he soaks loads of bibs while feeding when I burp him and spits up after for about an hour, I was worried out of my mind thinking how can he spit that much up and still be getting enough? I was told by the HV that since he wasn't stressed out by it and didn't have anything else wrong and was still putting on weight that he is known as a happy spitter, dunno if that's the same for you hun but thought I would say anyway xxxx
