Who looks after baby?

Hi Mummies and Daddies, can you guys share with me who looks after your baby once you resume back to work? What if both your parents and in-laws are not capable to look after baby due to old age? And financially tight to place baby in infant care or get a helper. Our BTO is still not ready so at the moment just both our parents home. How do you guys manage in this kind of situation? Or if you were in this situation?
