Unexplained tremors
My baby was born on August 22, 2005, and currently weighs 5000 grams.
1.
Over the past two weeks, my baby has been refusing to sleep at night and cries a lot.
After some straining, he passes gas and has bowel movements.
Could this be a sign of colic? How can I check for this?
2.
When I pat my baby's back, sometimes his legs tremble in rhythm with my movements.
Is this normal? Additionally, there are times when there is no loud sound, but my baby still shows a startle reflex, which makes me more worried.
3.
There is a noticeable difference in the number of skin folds on my baby's thighs (the left thigh has one less fold).
Could this indicate a developmental issue with the left leg?
4.
My baby has a hydrocele, and the right testicle is larger than the left.
Should we pursue further examination for this?
Thank you, doctor, for taking the time to respond!

Hello Annie:
1.
Infant colic is indeed more likely to occur in the evening, making it difficult to examine and diagnose.
It is essential to rule out any organ diseases before making a diagnosis.
It is best for newborns to be examined by a pediatric specialist.
2.
The startle reflex in newborns is normal up to 4-6 months of age, and loud noises or sudden movements can trigger this reflex action.
3.
In addition to the legs, it is important to observe whether other parts of the body are symmetrical.
For a baby over one month old, you should check if the movements of both legs are symmetrical.
4.
If hydrocele is confirmed, observation is sufficient, but it is important to differentiate it from a hernia.
Best wishes,
Dr.

Understanding infant tremors and common pediatric concerns is crucial for new parents, as it can help alleviate anxiety and ensure the well-being of the child. Let's address your concerns one by one.
1. Nighttime Crying and Gas: It's not uncommon for infants to experience discomfort due to gas, which can lead to crying and difficulty sleeping. This could indeed be a sign of colic or gastrointestinal discomfort. To check for colic, observe if your baby cries for more than three hours a day, three days a week, for three weeks or longer. You can try gentle tummy massages, bicycle leg movements, or holding your baby in an upright position after feeding to help relieve gas. If the crying persists or is accompanied by other symptoms like vomiting or a distended abdomen, it’s essential to consult your pediatrician for further evaluation.
2. Tremors During Back Patting: It's not unusual for infants to exhibit some involuntary movements, including tremors, especially when they are excited or startled. However, if the tremors are rhythmic and consistent, or if they occur in a way that seems abnormal, it’s worth discussing with your pediatrician. The startle reflex, known as the Moro reflex, is common in newborns and can cause them to flinch or jerk in response to sudden movements or noises. If you notice that the tremors are frequent or accompanied by other concerning signs (like changes in alertness or feeding), a pediatric evaluation is warranted.
3. Asymmetrical Thigh Creases: The presence of uneven thigh creases can sometimes indicate hip dysplasia, a condition where the hip joint doesn’t properly fit into the hip socket. While some asymmetry can be normal, especially in infants, it’s advisable to have your pediatrician assess this. They may perform a physical examination or recommend an ultrasound to rule out any developmental issues.
4. Hydrocele and Testicular Size Discrepancy: Hydrocele, or fluid accumulation in the scrotum, is relatively common in newborns and often resolves on its own. However, if one testicle is significantly larger than the other, or if there are other symptoms such as redness, swelling, or pain, it’s important to have this evaluated by a pediatrician. They may perform a physical examination and, if necessary, an ultrasound to determine the cause of the size difference and whether any treatment is needed.
In summary, while some of the symptoms you describe can be common in infants, it’s always best to consult with your pediatrician for a thorough evaluation. They can provide reassurance, conduct necessary examinations, and guide you on the best practices for your baby's health and development. Regular check-ups are essential for monitoring growth and development milestones, and they provide an opportunity to address any concerns you may have. Remember, being proactive about your child's health is key to ensuring their well-being.
