I know I’m waaaaaaaay late to the party so sorry😅
But I work at a daycare, and a great deal of the kids get very upset when their parents leave. Some of them can be consoled fairly quickly, or get distracted playing with other kids, but some kids, especially the very young ones, will just cry and cry and cry unless someone is holding them. Even then, for some of them it isn’t enough and they still wail. There’s one poor little guy who will attach himself to my leg the minute he comes and will cling to my pants the whole time he’s there. He won’t let go even to play with his brother. It’s probably quite normal for kids to get overwhelmed with separation anxiety, especially at such a young age.
