Mine did not thankfully.
My DS had moments when he was really bratty to his sister when she first came home we just made sure to give him one on one time with me(and or DH) and it seemed to help.Even to this day he still has his moments.
My kids are just shy of 2 years and 8 months apart. My son was fine with her until she got more mobile. When she was about a year he started biting her and that lasted a while. They are 5 1/2 and 2 years 8 months now and get along pretty well.
My oldest has issues more now than she did when my 2nd child was born.
