My almost 3 year old son has been having fluffy yellow very stinky bms for the past three days. His illness started with an episode of vomiting roughly 15 times in 12 hours last Thursday evening and has progressed to this. He s not eating well and just acts generally like he doesn t feel good. Went to doc and they have him zofran for nausea but said it would probably just clear up (before the bm change).
