Is it the daycare provider that is saying child is not adapting or is it what you are observing as in still crying at drop offs?

If this is your child's first time in care it will take them longer to adjust than if they had started when they were younger because they are more aware of the changes and in a sense is simply rebelling about having to go to daycare at all meaning it might not be any better with another provider.

It can also make a difference depending on how much exposure your child had to other kids, large groups, waiting, taking turns, not being the centre of attention, not having someone drop what they were doing and cater to their whims etc. Now they are part of a group which means waiting, eating on demand, not getting a choice of meals, doing certain activities as scheduled not when desired so a lot of adjusting going on.

Also make sure that your anxieties are not being seen by your child. Make going to daycare a positive thing. Speak with your caregiver about how your child does during the day and what parts of the day seem to be the hardest for him to handle so that maybe you can help him learn coping skills for that activity.

At the same time if you feel you are not able to work with your caregiver to solve the issues then maybe moving to a different type of environment is what you will need to do. Each child has their own personality and sometimes they come up against another person/child that is at odds with them. Some children thrive on a program with a set rigid schedule and others need a loosely planned day to thrive. Think very carefully about how your child learns and what kind of an environment would best promote that.
