I know from experience it can be difficult to incorporate the needs of one so young into the routines of a center. I purchased strap on infant carriers for staff which allowed us the opportunity to carry small infants yet keep hands free for mobile infant needs.
For some young infants - the noise, the lights, the activity can be overwhelming. Try a few room changes and observe if any help comfort the child. Try placing the child in a low light area, or just using natural light versus ceiling fluorescents, try a white noise sound like ocean waves or heartbeat rhythm, or try to separate activity into a noisy section and a quiet section of the playroom. I have also found it best to tell young infants what they are going to experience beforehand, such as "I am going to pick you up now" "This will be a cold wipe on your bum, ready" or "we are going into a noisy place now, brace yourself, ready here we go."
These may be things you have already tried. Hope you find a solution that works best for all.
