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?

Some Cc allow parents to stay while some dont .For me i accompany my girl for the 1st day to let her feel secure and adapt the new environment and people there.Inbetween i did walk out and mingle outside the school.For the 1st few days we brought her home earlier and slowly the time drag later. Crying depend on each indivual child, some can adapt new environment fast while some take longer time. For my girl she cried on off nearly 1month but now she loves school ..Normally after picking we ask her about her school,have more interaction about school to them . Labeling of all her school stuffs is important
