If your child does not settle
Young children are very clever, they learn to pull on your heart stings, knowing what works.  Young children will come up with a number of ways of manipulating you through your feelings.  Be aware that they may use statements like “I hate you”; “I hate Daycare”; “She’s mean”.  These are usually just ways to get their own way.  

It is a basic instinct of protection for them to behave like this.  Once your child realises that causing a fuss is not going to change things.  You still have to go to work, they will settle easier.  However, if your child continues to get upset when you need to leave, you could try to arrange for your partner or a friend to drop your child off instead of you.  It may simply be that your child is objecting to you leaving, rather than there being a problem with their child care environment.

Your child will come into contact with a whole new group of people and take part in new experiences in their first weeks of care and any one of these could influence their emotions.

It takes time for young children to adjust to child care, some children take longer than others.

Remember consistency and routine is very important for children.  Establish a routine and stick to it.  Don't try too many changes at once.  Let them get used to one change at a time.

Child care can be a fantastic learning and social experience for children, if they can learn to be comfortable in a small group, it will make going to school less of a hurdle.
