With the tiny pups that are having difficulties and having to fight for food, I've heard from others that they often will allow the little one to nurse first, for several minutes to give them a headstart. This will ensure that this little one is eating and getting his fill, especially since he's so much smaller than the others. Just an idea, it'll probably help out. I just saw the picture, they are soooo cute! Congrats again, aren't puppies just wonderful!?! I'm really enjoying having our little girls around; Maya is doing so well.
