My 2-month-old baby was diagnosed with moderate hydronephrosis in the left kidney showing a dilated renal pelvis and mild cortical thinning, possibly due to PUJ obstruction. The ultrasound showed the left kidney is 5.5x2.4 cm with a 14mm AP diameter of the renal pelvis and slightly reduced cortical thickness. The right kidney looks normal. Do you think surgery is needed or are there other treatment options we should consider first?

For a 2-month-old with moderate hydronephrosis due to a possible ureteropelvic junction (PUJ) obstruction, initial treatment often involves watchful waiting and monitoring, along with strategies to prevent urinary tract infections (UTIs). Surgery may be considered if the condition worsens, kidney function is compromised, or if other complications arise

I'm a breastfeeding mom with a 2-month-old baby, and I had a really bad migraine last night. I took Disprin and stopped breastfeeding for about 23 hours after that. I even expressed and discarded the milk I produced after taking the medication because I heard aspirin isn't recommended during breastfeeding. Is it safe for me to start breastfeeding again now?

yes

My daughter just turned 4 months old and she's been running a fever around 98.9 to 99.7 for 12 days now. I've been giving her Fepanil drops and Macpod since day one of the fever, but it hasnt gone away. Should I be worried?

I'm really worried because my 2-month-old baby accidentally swallowed one of my hairs. I saw it on his tongue and tried to get it out, but then he swallowed it. Is this something I should be concerned about?

It is important to monitor for any signs of distress such as difficulty breathing, coughing, or vomiting. In most cases, the hair will pass through the digestive system without causing any issues. However, if you notice any concerning symptoms or if your baby seems to be in discomfort, you should consult a pediatrician.
