How many siblings does Haley say she has back in season 1?

i know that theres at least 3 sisters quinn & taylor & vivian. but karen says haley has 5 brothers and sisters. but we never hear anything about any brothers..... so i dont really know. and lydia made it sound like she made a lot of stops before haleys

I don't thinkshe acuallly says but in season 1 when nathan is pacing her rooom he 's like are these all your brothers and sisters and haley's like ya im the youngest i dont think my parents know what to do with the silence I dont know why she never talked about her brothers and in 7.18 when lydia is talking to quin and haley she like well 2 out of 3 not bad . So its reallly confusing .
