Help with his son

So my boyfriend son just moved in with us for the school, which is ok I still have to get use to a third child in the house. I love every moment of him being here. this is my issue though my boyfriend help out with him but then he don't. Like he handle the home work part and he expect me to get him ready for bed, make sure he took a bath and things like that. Which is not a issue but he doesn't make an attempt to help out at all, like I will have to say "well jimmy it's time to get ready for bed". Now on top of that I have 2 other kids I have to get ready for school which one of them is 2. Btw the son is 6 and my daughter is 6. If I bring this issue to him he is going to think I don't want to do it, that's not the case I just want help..
