Back to school can be exciting… and exhausting. 🎒☀️

Earlier mornings, longer days, new routines, activities, and even this heat can leave kids a little more tired, hungry, or emotional than usual.

Some kids may need a snack, some downtime, or just a little space before they’re ready to tell you all about their day. 💛

Consistent meals and bedtimes, time to decompress, and a little patience can help as everyone settles into the new school year.

Here’s to finding your family’s new rhythm. ☀️

Happy National Dog Day from the pups who bring a little extra sunshine to our lives! ☀️🐾

Kip keeps Dr. Lee outside, active, and enjoying the little things, while Kobe and Winston make sure Dr. Bui always has plenty of love (and a little mischief 😂) waiting for her at home.

After busy days caring for kids, we’re pretty lucky to have these three waiting for us. 💛

Happy National Dog Day to all the pups out there!

At Sunshine Pediatrics OC, we believe in evidence-based care and protecting children from vaccine-preventable disease. 💛☀️

We follow the American Academy of Pediatrics (AAP) recommended immunization schedule and recommend vaccines because they are safe, effective, and one of the most important tools we have to protect children’s health.

We also know parents may have questions about vaccines, side effects, or timing — and those questions are always welcome. We’re here to provide reliable information and help families feel informed about their child’s care.

☀️ Evidence-based. AAP-guided. Focused on protecting kids.

A few of our favorite summer memories ☀️

From kayaking and family runs to bike rides and beach days with the pups, we’ve been soaking up a little sunshine outside the office, too. 💛

Here’s to enjoying these last few weeks of summer!

It’s the little things. ☀️

The fun Band-Aids. The sticker choices. A little sunshine in every room. And all the work that happens behind the scenes.

Just a few of the little details that make Sunshine Pediatrics OC feel like us. 💛

We’re so happy to care for your family.

Happy Friday!

Back-to-school season is almost here! 📚☀️

A consistent sleep routine can help make the transition back to early school mornings a little easier. Start shifting bedtime and wake-up time gradually, keep evenings calm and predictable, and give screens a bedtime too. 🌙

And don’t forget—kids and teens need more sleep than we sometimes realize!

Save this post for your back-to-school reset. 💛

🌞 With this heat wave, staying hydrated is more important than ever!

Kids can become dehydrated more quickly than adults, especially during outdoor play, sports, and hot summer days. Knowing how much water they need, recognizing the early signs of dehydration, and taking regular water and shade breaks can help keep them safe all season long.

Swipe through for:
💧 Recommended daily water intake by age
💧 Signs your child may need more fluids
💧 Simple ways to stay hydrated
💧 Heat safety reminders
💧 When it’s time to call your pediatrician

Remember that every child is different, and water needs can increase with hot weather, physical activity, and illness.

Stay cool, stay hydrated, and enjoy the rest of your summer safely! ☀️💙

Water intake recommendations adapted from the American Academy of Pediatrics’ HealthyChildren.org.

🤍 Happy National Friendship Day!

Before Sunshine Pediatrics OC, we spent years caring for Orange County families together. Along the way, we built friendships rooted in trust, respect, and a shared love of pediatrics.

Those friendships became the foundation of our practice—and continue to shape the way we care for every child and family who walks through our doors.

We’re grateful to work alongside friends who share the same commitment to compassionate, evidence-based pediatric care, and we’re even more grateful for the families who trust us with their children’s care.

Happy Friendship Day from all of us at Sunshine Pediatrics OC! ☀️💛
