Working Moms - Caregiver Jealousy?

Anyone having jealousy over the people watching your babies during the work week? LO is 11 weeks old Friday - dropped her off this morning and she was reaching and cooing at her teacher ... wouldn't even look back at me!! Broke my heart :/. I know everyone says they know their mama but she's just so little still how are we sure 😩😩😩.. don't mind my pity party over here!
