When my dd, now 6, was about 3 she would throw up once in a while for no reason. She would say her stomach hurt and then a minute later throw up. At first it was pretty rare. Over time it got worse. She'll go weeks, maybe months without throwing up. Then she'll go a couple weeks with throwing up once or twice a day. Now it happens in the middle of the night. Now it's usually bile.
I've kept a food diary, but it's hard to keep up for many months at a time. The only connection I saw was dairy. After getting a lot of dairy in her system for a few days in a row, she got crampy, had diarrhea, and would sometimes throw up. Those symptoms are pretty much gone now. The last week, I keep getting woken up hearing her throw up. I run in there, she's already got her bucket. I clean her up, she goes back to sleep. And sleeps a long time. And I keep her home from school the next day.
She has allergies. Like a pretty constant runny nose. She had allergy tests-skin pricks & blood work-done years ago. Nothing notable then. Dry, pale skin. No fever. No loss of appetite. Once she's slept well she's back to her normal self. What do I do? Is it time to kind of demand blood tests? Her pediatrician isn't super concerned b/c she's growing normally and doing well otherwise.
Any advice? Any experience with this? Any ideas?
