This happened yesterday. I found out right before I did a baby story time, that 38 babies were registered. That meant I'd have at least 70 babies and parents in my baby story time program. I had no clue how this was going to work because if one baby cries, the rest follow.
So when the parents and babies came into the room I said, "Ok, this will need to be a group effort. We're all going to have to keep all the babies happy for the next 30 minutes. Do what you can even if it's not your baby. I'll keep it moving and we'll see if we can accomplish this." I admitted I was very afraid of having so many in one room and laughed that this will be a feat if we all accomplished harmony.
Miracles on top of miracles, all 38 babies were happy and smiling and both them and their parents had a great time. My co-worker who helps me with the storytimes said to me, "You're good! I couldn't have done that!"
Now if I can make it 7 more times because we have this every Friday for 8 weeks.
