Too many kids?

along with my daughter, me and my girl have 4. i love all of them very much...and what a blessing!!!But...we never get a minute!!!! mom is under bombardment with either a fight in need of justice or just inquisitive minds seeking answers. 3 are young teens, one is 6. I love all my girls...but damn! usually i'm left just stunned all day as i can't even get a chance to gather my thoughts and i hate to see mom getting run over by this pink tsunami! she says she likes it!!!!!But daddy needs mommy too!!!! I'm looking for advice here!!!!!!!AAAAH!!!! can't we all just get along!!!!is my girl spoiling them? should i just roll with it? WHERE do i put my foot down...as we are a fairly new couple, though we've known eachother for a few years?
