Starting Daycare / sleep training

Hi mommies, I am so confused about getting back to work and where to leave my baby. Family is out of option since they leave abroad. She is 2 months old and still attached to me (breastfeed and also presence). I am worry if daycare will not accept my baby. I tried to train her sleep in crib but doesnt work yet, not even leaving her alone for 5 minutes without loud cry. Any suggestion mommies? I need to be in office by March. TIA #firsttimemom
