Are they in the same room with you? I recommend you ask to be in a part of the daycare where they can't see you, like can't see you from a window, won't have you walking through. If that's not possible then ask to be in their room. If they can see you and can't get to you they may never settle. I've worked in a day care with my kid there since 15 months, around 2 he went through a stage where he had to cling to me the whole time, he's grown out of it but there are still days where he wants me close.
