How to help a burnt out teacher?

My son has been a handful in Kindergarten this year. He has had better and worse periods throughout the year. The past month has been especially hard. He got sick and it’s like he just couldn’t get back to normal. The last couple of days have been better but it’s a day by day process.

I can tell the teacher is getting worn down. She is usually an upbeat, always positive, looks at the bright side kind of person. But over the last couple of weeks, I can see she is becoming discouraged, saying she isn’t capable or trained to handle such behaviors. She has started to pass it on to the counselor and principal. I totally understand this but by the change in the way she talks to me, I feel like she is giving up. She actually said that she saw this year going differently, that she and my son had such a good relationship. But during this past month when it has been the most difficult, he yelled at her that he hated her. Of course I know coming from a 6 year old, you never take those kinds of statements to heart. But I think she is very sensitive to it.

I want to try to boost her morale and truly let her know how appreciated she is. I tell her all of the time and she has acknowledged in the past that she feels appreciated by me and my son. But this has changed.

Any ideas are welcome. Thank you.

Edit:

Therapies available in our area are at the school, which is already being utilized. We don’t even have pediatricians nearby. But his regular family practice doctor seems to think he will grow out of it. I am 150% involved in every aspect of the situation. His father left in January for overseas to receive medical treatment until April. So although some are very rude with your assumptions that nothing is being done already and it is a parenting fault and that’s it, you only prove to not have the adequate information to form that opinion. The trauma of his father gone for health concerns and the fact that the troublesome behavior is only happening at school is the information that would have been important to know if your judgement or criticism had been asked for. But this post was about how to boost the young woman’s morale and let her know she is truly appreciated.

2nd edit in response to additional comments: assumptions that nothing is already being done! The doctor and referral specialist both agreed on the sentiment that he will grow out of it. No further evaluations at this time. The teacher, principal, counselor and doctor all agree that he is lacking regulation skills, attention seeking, testing boundaries, lacking self esteem, socially immature, academically ahead causing boredom and uncomfortable with how to express or communicate any of his frustration type of feelings. They believe he needs to practice. When I am present, he is completely regulated because I am his safe person and home is his safe place. So many assumptions. It wasn’t as simple as should I buy the teacher a coffee. She is a person too with real feelings about this situation. Boosting morale is an empathetic thing to do. That is why I asked for suggestions. I am ok with unsolicited advice but when all you do is fill in the blanks with assumptions, it just isn’t helpful to anyone.
