I agree ~ starting childcare is stressful for babies .... try to remember back to your first day of school or first day on a new job all those feelings of anxiety you had now imagine that you had no WORDS to ask for help, to express your feelings to a peer or coworker

Things to do to help ~ play lots of object permanence orientated games with them to help them master that what 'goes away comes back' so peek a boo games with items, with you. Hiding things under blankets and bringing them back out, leaving the line of site and popping back with the smile and the 'here I am'.

Having something that 'smells' like home for them to hold .... sounds gross but one of moms UNWASHED t shirts that she slept in for example .... kids are sensory orientated and being able to 'smell' mom despite her absence can increase their level of trust and ease anxiety being able to hold that and sleep with that might help to increase babes security.

Naptime will come too ~ to help the others I play solitudes music through the sleep areas to drown out any noise others might make and black out curtains in the sleep rooms to help them not be distracted by shadows or what not in the room. I had a new little one start in February who only slept 20 minute cat naps at home and within a couple of weeks was having 1 hour in the morning and 2-3 hours in the afternoon ... he just needed help to learn to self sooth back to sleep cause he would wake mid sleep cycle and cry out and mama thought that meant he was 'done' when in reality it was GAS waking him up briefly if you soothed him he would go back to sleep.
