Hi honey, firstly to you,
It is a hard situation and you are on the right track I have worked in long day care for nearly 13 years and I know that most children take a couple of weeks to settle in to a new environment, and as hard as it is it is easier for your child to settle when they know that mum is confident and happy that they will be fine and leave with a "mummy loves you and you will have a great, fun day and I will see you soon"
you may have tears for the initial few seperations(for both of you) talk with your carers and I can promise that the tears will not last all day and the more times you attend and stay positive and confident the easier it will get, If your carers are like me (and I hope they will be) they would call you and honestly let you know if your child could benefit from being picked up a little earlier or isn't coping as well on a particular day and we also encourage parents to call as many time as they want through the course of the day so you can feel confident that your child is happy.
good luck sweets and ulimately follow your heart
