How can i get my lazy husband to help me out with baby number 2?

hi im a house wife and i live at my mother in laws. i clean the messy room he leaves every morning when he leaves to work. i cook for my daughter and me and i wash and do what a house wife should do. i am expecting baby number 2. now people may think wow number 2 but i am only 20 and married to a lazy rude man. who swears all he needs To do is work. he is a teachers aid in a preschool in costa mesa. wow he deals with little kids. now he comes home saying i don't have to do not one thing and its sad. my question is what can i do or should do in this situation. i know men are lazy its in their nature but you are married and have kids its time to grow up. i know i did.
