Hey hun, tough isn't it?
Poor little chicken having all those teeth already!
Sadly I'm up to my second screamer. Some babes just cry - a lot. My two both started the separation anxiety thing from birth lol. You should see the show from Nate if I have to go to the loo! He won't even sit with his father for any length of time.
Also 6months is kind of an unsettled phase they seem to go through. They are becoming more aware of the world and themselves in it.
IRT the formula thing. It's just a guide babe. Don't stress. SOme babies don't eat anywhere near what it says, some eat way more.
