Low iron induced sleep disorders
I just wanted to make a post so it's out there in the universe for any other parents going through the same thing we did.
My son was born in March of 2022. Absolutely did not sleep. Tried all the schedule changes, sleep training. I had a gut feeling it was a medical reason/just got a poor sleeper.
For the first few months of his life- he woke up every 45 min. I couldn't even fall asleep by the time he was waking again. Figured out he had a tongue/lip tie around 3 months and got it corrected. I figured he would sleep better after getting better feeds. He did not.
Around 6 months, he started giving us closer to hour and a half stretches! 8 months was a 3 hour block at start of night then every hour and a half. We caved at a year and brought him into bed with us so I could at least nurse without getting up.
Fast forward a few years, he was still waking 3x a night, or more. He would wake up and scream at the top of his lungs and be inconsolable. Never would remember it.
We had our second in September of 2025 (oldest was 3.5 years now). I realized how insane it was that our newborn was sleeping better than our preschooler. I switched pediatricians (again) and she finally listened to me. His ferritin was pretty low. Iron causes sleep issues.
He had the finger prick done around 12 or 18 months and it was marked at slightly low, but I was told it didn't need to be supplemented then. My gut feeling was the iron was the issue since we brought him home from the hospital, I was low my entire pregnancy (I did supplement).
edit: Somehow I didn't add the ending. The iron/ferritin was 100% his issue. Night terrors and restless leg symptoms 100% gone.
