Mother of boys or boy mom to be

I need to know something very important..

My family have only girls and this time me and my sister had a girl same time. My friend told me if i ever do breakfast? And the answer is A big NO , me and my family have never ever done breakfast we just have lunch. So she told me that mom of boys do have breakfast they never skip. So all i want to know is there any other women who never did breakfast and still conceived a boy? I accidentally got pregnant this time again and i feel it will be another girl as i didnt have breakfast :(
