Tummy ache waking toddler

Well, my sleep battles just seem to go on and on. For the last few weeks, my daughter has been waking in the night, crying her heart out, so I pick her up and she farts and farts and farts then quite happily goes back to bed. Last night was a different story. She went to bed quite happily as per normal - goes down awake, self settles, and asleep within about 5 minutes. Come 8 o'clock, she woke. I left her for 5 minutes in case she went back to sleep. But NO! She cried so much, the front of her sleeping bag was wet. I got her up she farted for about 10 minutes, then wouldn't settle. Got her back up, more farts, wouldn't even settle while being held. Just screamed and cried for hours. Farts, a poo, more farts it went on from 8 pm until 11.30.mPoor wee thing.

What I'm asking is - can anybody suggest what I can do about the wind? Could it be because of dairy? I need some sleep!

Very regular! Goes twice a day almost every day (on a slow day it's only once, other days it can be three times.)
