I work in a daycare, so I can say from personal experiences, say goodbye, hugs and kisses, and leave! Don't look back or show that you are upset about leaving him there!! He will be fine. I have a 16 1/2 month old and it breaks my heart... b/c I thought she needed me more than she actually does!!! I thought her world would stop, she would be so upset, etc... but give her 5 min and she is off running and playing. It's hard to walk out of the room, hearing your child cry... but I promise, 9/10 times, they're done before you even get out of the parking lot. The other 1/10... well, it may take them a few more minutes, but then they'll forget why they were even upset. Daycare workers are trained to handle crying/upset kids. Especially at this age, they are so easily distracted. Just let Gavin know that you love him and will be back at (whatever time you normally pick him up). Even though he doesn't understand the concept of time, it helps to "train" them to acknowledge that even though you are leaving, he can trust that you will return. Good luck!!!
