stay home or stay at work

as
What would you do?  I just started a full time job and my daughter is in Day care.  My husbands brother owns a restaurant and offered him a job that will pay more than what he gets.  I think it's a bad idea because we've both worked there and Woeking with family doesn't work out.   My husband wants to quit his job - with a great company.   He wants me to quit my job that I JUST started - can't work part time so I can stay home with our daughter - who has cried all day at daycare and isn't eating.  He is just thinking about our daughter which is good.   I'm not sure how I feel or what to think about it.  My mom got me a job at her work so I'm worried if I quit than my mom will not be happy with me.  My husband suggested that I go back to school to get the degree I really want.  I'm worried to tell my family and they will be mad.    I know it's my decision but I can't decide.
