Totally agree with AAK. Dropping the scholarship would be the last option, IMO. Many schools have family housing, and it's possible the scholarship is flexible enough to be able to apply some of the housing allowance towards that, and loans and family help might help make up the difference. Once baby is old enough, a family housing situation would be a prime spot to take on one or two other children for some childcare income, and possibly even an exchange so GF can work or take some classes, and usually there is some childcare available through the ECE program on campus. I would not ditch this option until all possibilities have dried up.
