Husband help with costs?

Does your husband help/buy things for your child/ren? 
My so and I have a daughter and another on the way but he NEVER buys anything or help finacally with anything our eldest needs like clothes ect and now again with this bump he hasn't bought one item of baby essentials. I have had to buy everything and dos so with our eldest to or they would have nothing. He doesn't seem interested at all just concerned about himself.
