Sorry I am FREAKED out

Like some of you know, I lost one kitten this morning, I thought I was about to loose another one. My two kittens are BIG! They are at a healthy weight but I am a little concern. Tonight my girl kitten was in deep sleep, her tongue stinking out. That is not big deal because my cat Garfield does the same thing. But what is bothering me that the tip of her tongue is almost white. Her skin on her tummy and chest looks like it is sticking together a little. The boy's tongue sticks out too. Am I just being a freak? Is there anything I need to worry about? I am afriad to scare Angel from nursing her babes because I am so worried. There is nothing to be worried about, right?

Honestly I would call the vet now... White tongue doesnt sound right....
