My DS was the worst when it came to chucking. It never bothered him, but I literally couldn't pick him up without a spew cloth on my shoulder and we would both get changed at least 3 times a day and go through countless bibs and spew cloths. But then at around 5.5 months all of a sudden it got less and less, now he rarely has a spew. Don't worry too much, there is an end in sight!
