I would advise you to make an appointment with his pediatrician>> YES >> the stool should be checked if this has been an ongoing pattern but the doctor would probably prefer to have you collect in special container for sending to lab...
Loose yellow stool would not be normal pattern.. I agree with you on this point.
I hope that this is helpful for you.
Let me know if you have further questions or details of his problems or discussion and I will be happy to get back with you!
Thank you. Appreciated. Will do.
OK take care>> Let mme know if I may be of further help to you!
