Yes, agree with tremble. I expect at least 2 weeks for the transition period. It's a new home, new children, new daycare provider, no parents etc. It's stressful for kids and they need time to adjust. Sometimes it takes kids less and sometimes more. Anything over a month is excessive in my mind and I would likely start to consider asking the parents to find alternate care at that time. Thankfully I haven't gotten to that point yet...close tho! lol

I had an all day every day crier for two weeks. He cried ALL the time, even during napping, eating, playing etc etc etc! I would let him sit on my lap for short periods of time and I would play with him and encourage him to play with the others. As soon as he cried off my lap he went. There were times his crying was so out of control I could do nothing else but put him in his playpen. He would calm down a bit, enough to come back out, and I would get him and start the process over again. After exactly 2 weeks, he was great and is now the easiest child in this group and doesn't even cry at drop off's anymore and often doesn't want to go home!

Good luck!! Try many different things until you find what works best for you and the child. Most of us if not all understand how hard it is to have a crier!! Oh and I also drank a lot of wine after work LOL and I'm not a drinker!!
