hugs my dear...
i know a few ppl this has happened with and i think the baby eventually grew out of it?? some of them found it easier when they came out of the capsule and went upright - i know L had some refluxy type issues so maybe lying flat bothers him? what's he like in the pram (some of them also had pram issues and had to sit bubs up earlier?). does music help? maybe if he couuld hear your voice? i dont know what to offer, i hope he grows out of it soon. xxx
