I have a 2 year old in my care who goes bonkers if I am not in view as well. I continue talking to him and giving reassurance that all is well and I am right here while I quickly get accomplish my task. I have noticed that story time circle really helps him to learn to sit close but not on me and interact with the group and still feel secure.lts anlong process if I'm on my feet and he is not feeling 100% about it its a cry fest. its been a month and his parents think he's still in transition. nap time is time a horror show of screaming. it disrupts nap time and fills the house with noise. thankfully he is a short term contract !
6 hours is a long time to deal with crying, what do he parents say? are you able to get a nap in for a break? will he stop if you are holding him? for your own sanity I would plan with he parents a end date for care.
