2 full time jobs

If I have 2 full time jobs at the moment both are high paying jobs ( on my first job I already claimed the allowances that I am entitled and I never have pay to the IRS always get refund) , should I claimed 0 allowances on my second job? I don't want to owe to the IRS, also I am a family man have a wife that works part time and a 2 year old daughter.
