Dear K.,
I have a degree in Child Pysch. and Early Childhood Development and Education. I am a retired teacher from a private school, educating and nurturing children from ages 2 and 1/2 to 4 years of age. I also taught in the public school system in elementary at 3rd and 5th grade levels.
First thing you must consider is "why" he is well behaved during the time he is attending daycare? Are you absolutely certain that you are getting the proper information from his caretakers? Children will mimmick another child's behavior if he or she spend a great deal of time with them. This might be what he is experiencing and you might want to question the daycare with respect to that issue. Children live what they learn and if your son is around another child who is "spirited", he is just following by example. Especially if that example is being rewarded by the caretakers. However, if he behaves well while in the company of others only, then you might be in a better position to evaluate him.
Secondly, what method do you use to correct his behavior? Do you use "time out", take away games or favorite toys, etc. following any kind of unacceptable behavior? Do you also make it a point to "reward" him when he has behaved in a manner that pleases you?
Finally, once you have determined those two simple points...then you will definitely be ahead of the game. I will offer this information because you have mentioned it in your request...if your son is biting, hitting, and pushing, I must tell you that it is a sure bet that he is doing this to his playmates or others. That is why I questioned whether or not the daycare was giving you the information that you need in an effort to correct the problem. Children do not just randomly act out agressively like that in one venue, and change those "bad habits" in another.
I encourage you and your husband to speak to the daycare. If your son is in fact expressing this type of behavior while in their care, it will not be long before the daycare asks you to remove him from their care. Also, any method of punishment that you place on him prior to arriving at the daycare, should be discussed with the employees and carried out in your absense. Both you and your husband work, as many parents do, and you must have the daycare "on board" with you in raising your son. Let's face it...they are with him probably just as much as you are.
I hope that this advice works for you and please report back to me regarding your findings. I might be able to offer you further advice once you have your questions answered about your son. Before I close, please try to not beat yourself up over this. Sometimes its just a phase that some children go through and it requires a bit more patience. I can see that you are at your wits end right now, but trust me...brighter days are ahead.
