My 2nd is much worse than my 1st. I think their personality kind of shows as a baby, too, though, so I pretty much expected he was going to be worse, lol. He's been pretty fussy since he was a baby, and that hasn't improved. He's fine when he's happy and playing, but when he hits a bad mood, its BAD, and the tantrums are epic. DS1 was nothing like this.
