Transitioning can be so hard on wee ones ~ specially when they are not mobile and cannot move to a place that they feel more secure.

When I have an infant who is clearly beside themselves with anxiety about being in group care who is not been prepared for being cared for by someone beside mama or papa ~ I swaddle them and hold them and sing calmly trying to send them that reassuring message and create that bond of trust that they are indeed safe despite themselves, play lots of games of peekaboo and so forth to build up the reminder of object permanence that whatever disappears from view comes back ~ including me and mama and so forth. I try initially not to move out of arms reach until that 'screaming' in fear stage every time you move has passed in the first couple days and once they are no longer crying all the time cause they trust that their needs are going to be met than I slowly work on the independence of being able to move around the room without them loosing their noodle, to than leave the room without them loosing their noodle and so forth until they are finally a normal member of the group.
