Pretty sure when we drop off my son at daycare he's convinced we are going to abandon him.
Some days he doesn't care that we are abandoning him and happily plays and others days he does not like to be abandoned.
That's why he's so happy when we pick him up.
"You came back," he says in disbelief.
"Yep, we came back," we say.
"Yaaay," he says.
And then we repeat each day.
Until he is indifferent about us.
