Pushing SOS

[Spixie33]

I have three kids under 2 who are all within a few months of each other in terms of age. This is my second daycare group and I didn't have it with my first group but there is PUSHING INSANITY going on with this group.

Child A pushes Child C all the time. Often for no reason, sometimes because he gets too close.

Child C likes to alternate between smothering/hugging child B and pushing her.

Child B was great other than suffering through Child C but suddenly today she started pushing Child C away hard. I don't entirely blame her because Child C does not know how to keep his hands off of her and girls should be able to say no

But this pushing triangle is driving me batty. I am doing time outs, explaining that we don't push, giving the angry face, trying to show them the other child and show them that they hurt the child so they feel empathy, etc but NOTHING is working. We have done sorrys and hugs and everything in between but this problem is exhausting and it gets really bad when I turn my back.

Any suggestions other than a straight jacket for their hands?
