Any ideas what this could be?

[OhThisIsJustGrape]

DD (5) started being sick early hours of Sunday morning and continue until around 5.30am. By lunchtime she was bouncing around so had some toast but started being sick again around 4pm until 9.30pm.

Slept all night Sunday and yesterday was much better, managed a biscuit first thing, crackers and a few crisps at lunch and an apple later. Absolutely fine for rest of day, no nausea or sickness an even did a poo which was totally normal.

DD woke up this morning boiling hot although no temperature and has been sick again. No earache/sore throat/pain anywhere just lethargic and grumpy lol.

All seems strange and not really like a sickness bug - I would've thought she'd have brought her food up yesterday surely if it was a bug?

Any ideas?

I'd ask your GP, but likely a virus even without an obvious temperature, but if it continues, keep an eye on what you are feeding her & when she is sick/feeling ill, with view to thinking is it possibly the wheat you are giving her in biscuits, crackers etc, she could be intolerant/allergy
