Almost 3 Year Old Acting Out at School

a two year old acting out at preschool is not abnormal, even under the best of circumstances. What I would do is make sure your preschool program knows what is going on with you and her home right now. That will help them use extra patience. A little extra patience towards little children can go along way. Then I would follow the other advice given, let her cuddle with you as much as possible and explain to her that Mommy is getting better. You can even ask her to make you special pictures when she is at school because you love her art. Other than those two ideas I would speak to your parents and make sure they are following the same rules/routines you had set up for her before they came to help out.

You NEED to tell her Teacher/the group Leader(s).... so that they UNDERSTAND, your daughter and how her life is upside down now.
Otherwise, the Teachers will not know, nor understand.
With that knowledge, they may be better at facilitating her.
Tell them you are on bedrest and her Grandmas are helping you care for her. She is very very young... to be able to handle this. Their "emotions" are not even fully developed yet. Thus, they do not have coping-skills... as adults would nor like older children may have.

They cannot always DO, what they know, mentally. It is her age.

Let her lie down with you and "bond" with you. She needs you. And your comfort. She can just hang out with you in your room... talk with her and about anything. She needs, validation and to commiserate with you.

One thing we did with our son and his preschool teacher was institute a passbook. It was like a little mini journal that stayed in his backpack. It made communication with the teachers so much easier. It let them know when he was having a good day or a bad day. It let them know when he had rested well and when he hadn't. It let them know if something had upset him the day before in class that they didn't know about. It let me know specifically where areas of improvement were. How his day was. If he had an extra good day. I would write in it before school in the morning and they would write in it before he came home in the evening.

It helped us narrow down what was and wasn't working and in communicating more effectively with each other, we communicated more effectively with him. We were able to be specific with him about what he did, when, with whom, about what and why.

Behavior management is so important so don't lose your focus. There are good articles and blogs out there on this but the first thing you can think about is ABC, antecedent, behavior, consequence. Figure out what is happening, is the behavior due to avoidance/escape, or what, and give a proper consequence to extinguish bad behavior and replace with good! There are some really great blogs on behavior at www.NSPT4kids.com

I would just try to have lots of extra time with her cuddling, reading etc. She just needs more mommy time.
