Maybe your son used to run into school, and now he cries in the car every morning. Maybe your daughter has gone quiet at dinner for most of the semester and her bedroom door stays shut. You keep telling yourself it’s a phase. Some days you believe it.
Parents ask me all the time how they’ll know when to see a child psychiatrist. Usually it comes down to whether this is a hard season or a pattern that keeps getting in the way of your child’s life. Let me walk through it the way I would if you were sitting across from me.
What does a child psychiatrist actually do?
I’m a medical doctor, board-certified in both general psychiatry and child and adolescent psychiatry. That medical training shapes how I look at your child.
When a child comes to see me, I’m thinking about the body as well as the feelings. Sleep, development, a recent illness, school, home. Any of those can show up looking like a behavior or mood problem, and some are easy to miss if you only look at one piece.
So in practice, I evaluate and diagnose, help untangle concerns that overlap, and stay in touch with your child’s pediatrician and therapist so we’re all working from the same page. When it’s appropriate, I can also talk with you about whether medication might be one helpful tool.
Therapists do important work, and many of the families I care for have both a therapist and me on their team. I wrote more about how I think about the whole child in What Is Integrative Psychiatry?
How do I tell a rough patch from a real pattern?
Every child has hard days. Four-year-olds melt down at bedtime. Ten-year-olds lie awake before a big test. Fifteen-year-olds vanish into their rooms. Most of that is normal.
When a parent describes something to me, I listen for a few specific things. First, how long has it been going on? A few rough days after a move or a friendship falling apart is different from something that has hung around for weeks or months.
Next, how big is it for your child’s age? A worried kid who can be talked down is in a different place from one who can’t get out the door.
I also ask where it shows up. Trouble in one class is different from trouble that follows your child from home to school to practice.
And I want to know what it’s costing your child. Is it getting in the way of sleep, learning, friendships, family life, or how your child feels about themselves?
If the answers are “a long time, more than I’d expect, in more than one place, and it’s getting in the way,” it’s reasonable to ask for a professional look. You don’t have to be sure something is wrong first.
The American Academy of Child and Adolescent Psychiatry (AACAP) has a good parent resource on exactly this question, and the National Institute of Mental Health (NIMH) points out that early attention to a child’s mental health can make a real difference.
When to see a child psychiatrist: signs I’d want to hear about
These come from the kinds of signs AACAP describes for parents. They aren’t a checklist for diagnosing your child. If several sound familiar, that’s a reason to talk with someone. Nothing more.
In younger children
- Frequent, intense tantrums or irritability that seem out of proportion and are hard to recover from
- Worry or fear that keeps them from playing, sleeping, or separating from you
- Trouble paying attention, sitting still, or following directions that keeps showing up at school and at home
- Ongoing sleep problems or nightmares
- Frequent stomachaches or headaches without a clear medical cause
- Repeated aggression toward other children
- A noticeable change in behavior after something stressful or frightening
- Pulling back from play or friends they used to enjoy
In teens
- Sadness, irritability, or hopelessness that doesn’t lift
- Withdrawing from friends, family, or activities that once mattered to them
- A big drop in grades, or a new habit of avoiding school
- Major changes in sleep, appetite, or energy
- Worry, panic, or repetitive thoughts and rituals that eat up a lot of the day
- Alcohol or drug use, risky behavior, or trouble with the law
- Self-harm, or talk about death, not wanting to be here, or suicide
That last group needs a prompt response. Please see the crisis section below.
Why see a psychiatrist instead of only a therapist?
Plenty of children do well with their pediatrician and a good therapist and never need me. When families do come to my office, the picture is often complicated. The symptoms are strong, or they keep changing, or they haven’t budged with good support in place.
Often more than one thing is going on. A child who can’t focus may actually be anxious. A child who seems anxious may be exhausted. I want to understand the whole picture before anyone puts a name on it.
Some parents want to know whether medication could make sense as one part of a plan, or their child already takes something and they’d like a thoughtful second look. Others need a clear answer to a diagnostic question, like whether this is ADHD, anxiety, a mood condition, or something else.
Whatever brings you in, I want you to leave understanding your child better and holding a plan you feel good about. A prescription pad is never the goal.
Where should we start?
If you’re unsure, start with your child’s pediatrician. I spent a few years as the in-house child psychiatrist in a pediatric group, and I have a lot of respect for what pediatricians catch. They know your child’s history and can check for medical causes.
It also helps to ask teachers, coaches, and school counselors. They see a side of your child you don’t.
Before a first appointment, jot down when you first noticed this, what makes it better or worse, and what a school day looks like now. Notes like these help me see your child through your eyes. I also review intake forms and any records you send before we meet, so our time together can go toward listening.
You’re welcome to reach out to my office directly, too.
Does asking for help mean I’ve failed as a parent?
No. I say this plainly because I hear the worry so often. Asking for help means you’re paying attention. It doesn’t mean you did something wrong, and your child isn’t broken. Your child is not a diagnosis. I believe every child carries a dignity that doesn’t rise or fall with their hardest day.
Coming to see me also doesn’t mean your child will be started on medication. Some families leave with a clearer understanding, a few things to try at home, and a referral for therapy. That’s a good outcome.
When medication might help, it’s one possible tool among several, and we decide about it together, with your questions answered first.
How do visits work in my practice?
I see children ages 4 to 11, adolescents 12 to 21, and young adults 22 to 45. Much of my work is with ADHD, anxiety, depression and other mood concerns including DMDD, PTSD, and OCD. You can read more about my background on Who I Am and how I work on How I Serve.
My office is at 5300 Town and Country Blvd #240 in Frisco, and I see families from Frisco, Plano, McKinney, and across the Dallas–Fort Worth area. I also offer telehealth for patients in Texas and Colorado. The patient needs to be physically located in Texas or Colorado at the time of each visit.
My practice is private-pay and out-of-network. I provide superbills you may be able to submit to your insurance. Details are on How I Serve, and my FAQs page covers the questions parents ask me most.

If your child is talking about suicide, has hurt themselves, or you’re worried about their safety right now, please don’t wait for an appointment.
Frequently asked questions
Does my child need a psychiatrist or a therapist?
Many children benefit from both. A therapist works through talk and skill-building. As a psychiatrist, I’m a medical doctor, so I can also diagnose, look at medical and developmental factors, and talk with you about whether medication has a place.
Can I start with our pediatrician?
Yes, and I often recommend it. If the concerns are complex or don’t let up, your pediatrician may suggest a specialist, or you can reach out to me on your own.
Will seeing a psychiatrist mean my child goes on medication?
No. An evaluation is about understanding your child. Medication is one possible tool when it’s appropriate, and we decide about it together.
What age can a child see a psychiatrist?
It depends on the concern. In my practice, I see children starting at age 4, along with teens and young adults up to age 45.
