My 14-month old toddler did not behave normal after eating meal containing butternut squash, egg, pear and spinach. Last night she choked after eating the same meal and threw up the entire dinner. After throwing everything out, she felt better and was her normal self again. We were not sure whether it s food or the accidental choking, so we served the leftover for lunch today. 20 minutes after lunch, she acted very cranky and tired, lots of hiccup, swallowing, yawning and a bit coughing. After resting for an hour, she is now back to normal. Are these allergic reactions or potential food contamination? Do we need to see a doctor soon?
