Daycare for toddler

Hello mothers so I just need to get this off my chest and see what other moms think. My 2 year old has been going to daycare for 2 years now since she was a newborn. She’s an only child and she is very spoiled by family members and grandparents. She does have a good temper tantrum where she does have to be put on time out when she’s at daycare. She goes through stages when dropping off for daycare where she will just walk right in and give a hug good bye or the other stage where she will be crying going in doesn’t wanna leave my arms and I have to sit there to help her calm down. I honestly feel so overwhelmed when she crys and just don’t know what to think. I know the place I take her to is great and her teacher says that once I leave she stops crying and starts to go play. I just want to see if this common cause for my daughter it varies she will either be happy going in or crying dreading going to daycare! 😩😩
