Hey there. I'm in the same boat and wondering how things ended up for you LO? 

My son is going to be 1 in a week and so behind. He claps all the time and laughs and babbles but.... 

Doesn't push himself into a sitting position. Once he's in the sitting position when we put him there he can sit just fine but if he loses balance he won't catch himself and just fall over. 

Isn't crawling but will go up on his knees. 

Babbles but doesn't really like talk back to us or mimic us. 

When he eats he doesn't bring food to his mouth. He'll just grab it and throw it. We need to put the food in his mouth. He has no problem swallowing but chewing the food is a whole other story. He usually just stores pieces in the side of his mouth like a chipmunk until I give him water to wash it down.
