Hi, for a 2 year old boy that had colics and reflux till he was 1 1/2 year old; after going to the beach-the next day- vomits his breakfast(simple white toasted bread, a boiled egg, a small glass of bongurt(a yogurt-like product)(this is more or less a normal breakfast for him, but usually eats with the above,give or take one, plus a fruit(like a banana) and another protein or carbohydrate or cereal).He went to #2 as soon as he woke up (a bit soft but not really abnormal feces); yesterday he drank seawater(he was enjoying the beach too much) but he also ate some snacks for the first time(the restaurant where we had planed to eat was closed): 1cm of a chicken vienna sausage, and 7 doritos(pieces). After going home(1:30 hours after) he ate a normal dinner. Grandma gave him a bit of chocolate(hersheys milk bar). He asked for his milk bottle (usually milk with nestum cereal)before sleeping-1hour later- but I thought he d eaten too much-his stomach was big) and gave him only 3 ounces of milk without cereal. He went to sleep normally, woke only once at night(this normal 2 to 3 times a week, he likes to come to our bed at 4-5 am). He has no fever, no other symptom, and has only vomited today s food. Gave him 1onz of Pedylite, and some water, he has not vomited them. He seems to be vomiting mostly the egg, but it was not a bad egg and looked allright, I had one too from the same batch and it semt fine. My mother says it might be the seawater, specially since the last time we went to the beach he also vomited (but only one vomit) the next day. He sometimes has gagged a bit when eating boiled eggs(and red meat-but not with chicken or fish-) but this time he had already swallowed the egg, stood up to play(he is very active) during his breakfast, but suddenly looked bad and vomited. Could it be the seawater? If so, why didn t he vomit yesterday? I m alert for any symptoms but so far he s playing normally, being a normal crazy toddler like always.He looks a bit tired but I think it is because he had a busy day yesterday plus the vomit. The last month he weighted almost 30 pounds.He is tall for his age, around 90.(He looks like a 4 year old).
