The past couple nights, Natalie has been waking up and crying for about 30 min!!! :(
We're suspicious that she might have GERD, Gastroesophageal reflux disease. It's a more severe form of heartburn/reflux. They had it as babies, but Natalie had a slight case and Kiley's was worse, so it's wierd that Natalie's having trouble.
Tonight Natalie confirmed that it is deffinetely her stomach, she kinda pulled at it while we were reading books, and you could tell she was frustrated about it. :(
So, tomorrow, I'll have to call their ped and pray that he will be able to correctly diagnose what is going on. :S
