Daycare settling-in period for a 2-year-old: how many rough mornings did you have — looking for recent parent experiences

We started daycare this week and drop-off tears are hard to watch. The teachers say the child settles within ten minutes, but I still feel terrible leaving. How long did the adjustment take for your toddler, and did shorter days help initially? I am trying to decide this week, so practical details would help more than general pros and cons.
