Ahhhh now I see the other thread you were talking about.
This thread along with the other one is very reminiscent of what I went through in my day yesterday. The new DCK that started is also 1 year old...seemed fine at drop off and suddenly became a velcro on me and would scream like murder if I even broke contact.
I was about to call my own daycare providers that I used when my children were 12 and thank them because they must have had a He&& of a day that first week or month too but they never let on. I think anyone transitioning a 12 month old deserves to get a gold medal at this point. LOL
