hi my little girl had this at about 2 years,i can totally symperfise with you cas it is awful i slept next to her bed for 2 weeks in fear she would choke on her sick as she would vomit every hour or more, how old is your little 1? i found with my daughter ice pops really helped as they soothed her sore throat from constantly being sick gave her a little sugar for energy and it helped a little to re-hydrate her, i was told not to worry at all with food, once they are ova it there appetite does come back. xxx
