Hi there, sorry it took so long to get back with you. I found something similar for you on the www.parenting.com website. If you click on ages and stages and under the 2 year old section there is an article on Daycare jitters and advice. Also, found one on Balking at Daycare adn stopping stranger anger. They have several interesting articles on different types of growth and development issues. Best of luck to you both.tmv
At this age they are learning to express theirselves and they also learn quickly how to respond from reading your body language and reactions. I think that he may be saying that he prefers to be with you, but doesn't know how to tell you that. And maybe upset if you are the one that takes him to daycare, he may be upset because he chooses to be with you. But, he will adjust. They do go through so many phases of growth and development. I have a great book from college nursing course, but I haven't found something online yet for you. But, I'm sure that they are out there. He may also be struggling with trust as trust is built by repitition and staying home when sick, although it can't be helped, makes him have to adjust all over again upon entering the daycare. Also, this may be his way of dealing with the separation anxiety that often goes along with this age. I would really be surprised if it were more than just this normal emotional growth and development. Just be consistent and hang in there, more phases will follow and it is healthy for them.
It could be just his age and adjusting to daycare. Also, though, it could be that something is going on and he is trying to express this to you- whether it be that he is sad not to have mom around or that something is going on at the daycare itself. I would do a "surprise" drop by of the daycare center a few times over the next few weeks. You don't even have to let your son see you, just check up on what is going on there. My son also had the same problem--turned out that the daycare was making the kids put their faces to the wall or to the floor and was screaming at them to "shut up". He cried so much all the time, I thought something was up too. I pulled him from the daycare as soon as I discovered this.
Sounds like normal transitioning. And don't take it personally if he 'rejects" you. That is a good thing. It means he is happy at the daycare.
