Call the Roto Rooter

Well, I took Jack to the pediatrician. He doesn't have an ear infection but both ears were filled with wax. They are now clean. He smiled as they were cleaned. He also helped with the 'heart test' and let the doctor feel his belly.
He has a low grade temp. He hasn't gained any weight since January.
The doctor didn't feel any mass in his belly or bottom.
He is going to start Erythromycin for poopy problems next week. It's supposed to help Jack's poop 'move' through his gut. He's still clogged in the plumbing area. The cause might be his meds (Clonodine) we are using for sleep. Enema tonight (really don't want to do this) then a trial without the sleeping med for the week (we are to try Melatonin or 7.5ml of Benadryl). Then we start the Erythromycin.
Jack went to school . He almost puked on the way out the door. He hasn't eaten his formula over the last two nights (each night feed is half of his daily caloric intake). He's not tolerating his daily feeds well. He fusses and cries and once I stop the pump he sleeps. I think it's time for a new GI doctor.
