LO (15 months) has had a stomach bug since Wednesday. She's mostly better, but every morning, when we get her up, we find that she's vomited at some point during the night. It doesn't seem to bother her and it doesn't even set the monitor off. This happened with the last tummy bug she got, too.

Here are the details:
Wednesday night she vomited about 15 times overnight. It was awful.

Thursday, she was mostly better (no vomiting after 4am; really nasty diarrhea). We limited her to liquids (water and breastmilk; she won't take pedialyte).

Same on Friday. Vomited once when we gave her too much BM in short order.

Yesterday, we gave her some applesauce and the liquids. Fine, but had a tiny amount of vomit about 30 mins after her last bit of applesauce.

Vomit in bed (very small amounts) every morning at wake up.

What am I doing wrong? Should I be pushing more solids? Is the overnight vomit because she's hungry? Keep on doing what I'm doing?

Help!!
