dd is now 7 and had reflux as a baby. She didn't tolerate lumpy foods until a year and even then was liable to cough and be sick easily if she swallowed hard or has a cough and also has been occasionally travel sick.
Her latest episode involved an M and S sandwich yesterday (sorry to anyone who was in the cafe at Bluewater at the time !). She was hungry and thirsty but nibbling at it, then took a large bite and chewed when cajoled. She is perfectly well, apart from losing her front teeth and recovering from a cough. I have been worried it may be an attention thing and at times deliberate, but she insists not. Am at a loss now tbh, we generally just ignore and clean up, so don't make an issue of it, but wonder if there is more to it.
