My DD is 12 months and for the last week has been inconsolable at night. It looks like she has wind or stomach pains, she goes from pulling her legs under her while laying on her belly, to rolling around thrashing trying to kick her legs out.

She's been farting a bit, but it doesn't seem to offer much relief. I just don't know what to do :/ she's miserable and she can't sleep because of it.
She has been sick too, but I'm starting to think the two are unrelated. She's been back to normal today, but as soon as bedtime hit she's been screaming again.

Has anyone had something like this happen before?
