will Layla ever get better???

Layla has not been feeling well all week. Monday she started throwing up and hasn't stopped. Luckily she has not thrown up today(sunday). I was really concerned about her on thursday. Wednesday night she went to sleep at 4:30 in the afternoon, and didn't wake up until 8 in the morning. I kept going in to check on her to see if she was still ok. Thursday after her nap she woke up with purple and cold hands and feet. I gave her a bath hoping to warm them up and called for a doc apt. Everything was better than I thought, she was just really dehydrated. She didn't have a wet diaper all day and wouldn't drink formula and threw up gatoraide. so I got some pedialite in singles with a straw and she finally would drink out of a straw. I bought new formula wondering if it was the new formula I got for her (her stomach is so sensitive) her tummy is getting better but man she just cries and that is all around stressful. She is not herself, I don't know what else to do. Her feet are better she has had wet diapers but she still is in pain. Addie said she wasn't looking forward to being a mom to soon, and although that is a good thing right now :) I told her being a mom is the best and most challenging thing in the world.
Rhen, frustrating, stubborn, sweet boy that he is just yells, LAYLA be quite!! He won't listen when I tell him to leave her alone she is sick, so she is screaming and he is yelling. Wow, it has been a week.
