My 19mo toddler is going full day childcare soon. Is there anything I should take note of? Should I accompany her whole day on her 1st day?

See how it goes? My girl totally went on her own, play on her own with friends, i'm not inside she also Nvm. 12pm after lunch, go home. Next day, try to let her nap in school, but she can't slp, hence the school told me to pick her home so she can nap, hence she nap on the way home. next day successfully nap in school. Next week.... Cry like i abandoning her away... After awhile, ok to stay.. She have been crying till now whenever i send her to school, but if my Gmil send her to school, she is perfectly ok... Now if i send her to school, i give her a pack of sweet to hold till she reach school, so on and off she went to school without crying much.
