Major Mom guilt

Both hubby and I are self employed so weve both had to juggle going back to work. Daughter is 11 weeks old and I'm back one day currently but now we want to buy a house (and our bank account is dwindling) and live in such an expensive city, therefore gotta work more. On one hand, I'm looking forward to work because I love my job but I feel SO guilty. It makes me want to cry! We take turns watching her as we pick our own schedules so that's peace of mind at least...
