I have to agree with Daycarewhisperer...I often see day three as "D Day"...the day many kids are likely to suddenly resist being dropped off. It suddenly sinks in that this thing is going to be thier new reality...every day! For the first couple of days they are kind of stunned and distracted by the newness...and then it hits them "Whoa! Wait a minute...just because I didn't cry, doesn't mean I want to go here every day! Maybe I better cry and let my parents know that this is totally not okay!". I even saw this reaction with my own 2 year old when he was in daycare and we had to switch to a new daycare...the first two days were great and I started to breath a sigh of relief...patting myself on the back for choosing a great daycare. Then, day three, and whamo...crying tantrums..not wanting to go to daycare...saying he didn't like it there. It eventually passed, but there were a few difficult mornings!
