Welcome!
Since you have noticed he is like this with every provider, the changes will have to be made by you and your husband. Crying as a coping mechanism is normal but you will have to help it along. I would suggest a few things, and maybe others will have more, or better ideas.
1. Make drop-offs and pick-ups as fast as possible. No lingering.
2. If possible, stop coming by to nurse during the day. Bring bottles of pumped milk instead.
3. While at home encourage floor play, playing with toys, being independent.
4. You can still pick him up obviously, but try to limit it. The providers cannot carry him around all day since they are caring for multiple children. If you want that level of care, you will have to find a nanny.
I really hope he adjusts well to his new daycare.
