My grandaughter has choked so many times in her short 19 months of life. Now she is getting bigger, she puts her fingers in her mouth and pulls it out as sometimes it's a bit stringy.
This is a very common symptom of reflux. Usually this only affects my grandaughter when her meds need sorting out (kids medication is weight sensitive). Perhaps if this is happening a lot to you, you could ask your doctor if there is any other drug etc that you could try.
Have you been advised to avoid chocolate, alcohol, caffeine, spicy and fatty foods etc? Do you have your bed elevated? All this things can dramatically reduce symptoms for some refluxers.
