I have a 5 month old son. We have just been on holiday and tried to leave him with a baby sitter for 2 hours (so we could have dinner) but each time we were called back within 30 minutes because he was inconsolable. He'd been fed just before we handed him over, had a clean nappy and no other obvious causes for distress and settles within seconds of myself or my husband taking him from the baby sitter. Any suggestions on how to deal with this? We don't often leave him with a sitter but I have to go back to work in August and am worried how he'll cope with the nanny.
