So I have two step sons, a daughter of my own and a little boy on the way. They all have the same father. My question or vent, now that halloween is over and Christmas is sneaking up quickly. Should I have to spend the same amount on his older two that I do on my own two. My reasoning behind not wanting to be financially responsible for his older two and wanting to focus on My two is this: his older children have mothers. Mothers who not necessarily spoil but they do make sure the boys get what they want.
