I typically expect a transition period to last up to 2 weeks. Most of my hdc children have adjusted much quicker than this but there are some children who need longer. As long as I see improvement, I can bear with it and keep hoping that the next day will be even better. If there were no signs of improvement though, I would consider telling the parents within the first 2 weeks that if there was no sign of transitioning within the first month that they would have to find alternate care. Just like adults don't always mesh well with others, kids are the same. It doesn't mean that we failed, it just means our daycare and the kids personality don't get along.

Good luck!!!
