can drinking orange juice at night cause upset stomach in the morning? . my child has been waking with an upset stomach in the morning that lasts a few hours. she's been drinking natural orange juice with pulp at night. not sure if there is a connection. sometimes when i drink the oj late at night my stomach is a little crazy in the morning.
try a few nights without the orange juice and then try it again. if you do find a connection then just don't give oj at night. for most people this would not be an issue but it may be for you and your child.
