Hello, For the past 5 out of 6 nights My 3 1/2 year old son has been waking up at the same time every night (around 2:30 am) and crying for me then throws up a lot all over his bed. Once I take off all his dirty sheets, he falls right back to sleep. He wakes up in the morning and goes on with his day with no problems and no other symptoms of sickness. He normally does not eat that much....Normally for Breakfast he eats cereal, waffles or sausage links, lunch chicken nuggets or pizza, dinner chicken with rice or something to that extent. He normally drinks, milk, chocolate milk, juices throughout the day. Since he has been throwing up I have been substitute the more greasier foods to try and help the problem. But still seems to be throwing up. Any suggestions?Thank you so much for your help,Amanda
