Hairy Situation!

I have to admit, I am worried.  I am not sure what will become of Steven's hair.  Poor baby has his daddy's curls but really only in the back...but on the top and sides it is straight!  Ok, so the straight part has a little body to it but nothing like the CURLS in the back.  I would like for the sweet mess to get a hair cut but daddy says NO...and grandma and grandpa too :-)  But I am warning everyone now, the first mention of a mullet and off it goes!!!!  I really must post a pic of it.  It cracks me up and makes me nervous all at once.  What if it stays this way?  Any suggestions????
