I have a 5 year old girl and she whines about everything my son is 2 and he's not half as bad
my first son cried from the minute he was born until he could walk...that was a long year! my daughter was and is an absolute angel, she fed and slept, I didnt even have any trouble from her when she was teething. My second boy is 4 days old and has been good as gold so far...I think it depends more on the baby and how relaxed mum is than the gender.
When i had my daughter, she was my crybaby lol! I guess it depends on the kid...not sure, but when i had my son he did cry in the beginning and he cried more than my daughter, but i soon discovered that it was because his stomach couldnt handle the formula! When i switched to sensitive formula he slept thru the night, took good naps during the day and was all in all a good baby! he rarely cried (only cried when he was hungry) but that was it. I have friends who have little girls and i remember all of them being crybabies!
Im pregnant with my first but with my sisters kids (2 girls 1 boy) my nephew definately was more whiney. But really you wont know until you have him. I thibk any baby can be whiney
