The most useful detail in your description is the one you probably think is irrelevant: it only happens at work. The baby, the house, the evening routine — all fine. That pattern points away from a damaged memory and towards attention. And at a year postpartum, with things getting worse rather than better, it deserves a blood test before you file it under "this is me now".
Not medical advice — consult your doctor for personal guidance.
Why "Only At Work" Is the Clue
Consider what your memory at home actually has to do. The evening routine is the same sequence, in the same rooms, hundreds of times over, with the baby standing in front of you as a reminder. Almost nothing new has to go in, and what does is cued by something you can see.
Work is the opposite. A colleague explains a process once, out loud, at four in the afternoon, while you are half-tracking two other threads and a message you still owe someone. That information gets one unrehearsed pass, and it has to be encoded while your attention is already divided. Memory research is unusually clear on what that does: dividing attention while information is going in greatly disrupts later recall, while dividing attention during retrieval of something already learned has much more modest effects.
So you are not failing to retrieve your colleague's explanation — on that evidence it was never properly laid down. Losing track of where you saved a file is the same shape of problem: at the moment of saving, your attention was elsewhere. "My memory is going" and "new information is not getting in cleanly while I am loaded" lead to completely different places. No study has tested your exact pattern, so take this as the best available reading of it, not a diagnosis.
What the Evidence Actually Says — and Where It Is Thin
A 2022 study in the Journal of Women's Health compared forty-three first-time mothers at one year postpartum with forty-three non-mothers and found that mothers and non-mothers showed no significant differences on measures of objective cognition — even though the mothers rated their own memory as worse. That gap between what mothers report and what tests detect is one of the most reliable findings in this literature.
Where tests do pick something up, it is selective. A 2007 review pooling fourteen studies of pregnant and postpartum women concluded that memory measures placing relatively high demands on executive cognitive control may be selectively disrupted — not memory across the board. That review studied pregnancy and the early postpartum period, though, not women a year out and back in an office. It describes a mechanism that may apply to you rather than a finding about you.
Put plainly: the research supports "effortful, attention-hungry tasks are where this shows up" and does not support "your memory is damaged". It is a small, mixed field, and anyone who tells you it is settled is overselling it.
"It's Just Baby Brain" Is Not an Answer at This Stage
A real phenomenon existing is not a reason to stop asking why yours is getting worse. Something that is supposed to fade does not explain a symptom that is increasing. Three ordinary things can worsen exactly this presentation over a year, and all three are checkable.
Sleep. Broken sleep counts, not just short sleep. The US National Heart, Lung, and Blood Institute puts it simply: when you are short on sleep, you might have trouble learning, focusing, and reacting — the exact triad you describe.
Mood. The most commonly missed cause of this picture, and it does not require feeling obviously sad. The US National Institute of Mental Health lists "difficulty concentrating, remembering, or making decisions" among the common symptoms of perinatal depression, and the NHS states that postnatal depression symptoms can begin while you are pregnant, soon after birth, or up to a year after your baby is born. Anxiety does the same: the NHS lists finding it difficult to concentrate among the symptoms of generalised anxiety disorder. We cover the early mood window and treatment options separately.
Something physical and boring. Which brings us to the tests.
The Tests to Ask For by Name
"I'm forgetful" gets dismissed in a six-minute consultation. A named list does not. Take this to your physician and ask for it as a panel.
| Test | What it is looking for |
|---|---|
| TSH and free T4 | Thyroid function, including postpartum thyroiditis |
| Ferritin | Iron stores — the number that moves before haemoglobin does |
| Complete blood count | Anaemia |
| Vitamin B12 | Deficiency affecting cognition |
| Vitamin D | Commonly low in India; usually run alongside the rest |
Thyroid first. Postpartum thyroiditis affects about 1 in 20 women during the first year after giving birth, and the underactive phase can cause trouble concentrating — symptoms the NIDDK notes may be mistaken for the "baby blues". Note the window: this starts after birth, so a normal thyroid result during pregnancy tells you nothing about now. The same institute is clear that hypothyroidism cannot be judged from symptoms alone and is confirmed with thyroid blood tests.
Then iron — ask for ferritin, not only haemoglobin. Anaemia among Indian women of reproductive age is common and rising: one analysis of National Family Health Survey data reports it went from 53% in NFHS-4 to 57% in NFHS-5, and the NHS lists tiredness and lack of energy among its symptoms. Depleted stores matter even when haemoglobin looks acceptable: a randomised placebo-controlled trial in the BMJ, in 144 non-anaemic women with unexplained fatigue, found they may benefit from iron, with the effect restricted to those with low or borderline serum ferritin. That trial measured fatigue, not memory, and its participants were not postpartum — so it is a reason to check ferritin, not a promise about recall.
B12. The NHS lists "problems with memory, understanding and judgment" among the symptoms of vitamin B12 or folate deficiency anaemia. Especially worth checking in a largely vegetarian household.
Vitamin D, with realistic expectations. It is routinely added to this panel in India and worth correcting for other reasons, but be clear-eyed about your memory: a 2021 systematic review of twenty randomised trials concluded the evidence does not support a role for vitamin D supplementation in enhancing cognition in adults.
Your Notes and Recordings Are a Professional Skill
Capturing information as it arrives is the correct fix, not a crutch. Photo: RDNE Stock project on Pexels.
You described writing everything down and recording meetings as though it were evidence of decline. It is the opposite. If the weak link is information going in while your attention is split, capturing it as it is spoken is exactly the right intervention — and plenty of people with no postpartum history do the same thing because it works.
Keep doing it, and add one habit: before you save a file or close a conversation, stop for three seconds and name where it is going. That pause is the undivided attention the encoding needed. If your setup at home adds to the load, our guide to working from home with a young baby covers the logistics.
Questions Parents Ask
Is this just "mom brain"? Not in the way the phrase implies. At one year postpartum, mothers rated their memory worse than non-mothers but showed no significant differences on objective cognitive tests. The experience is real; a measurable deficit usually is not.
Why would it be worse now than at six months? Because the load changed when you went back to work, and because some causes start late. Postpartum thyroiditis appears during the first year after birth, and postnatal depression can begin at any point up to a year after your baby is born.
Could low mood be behind this even though I do not feel depressed? It can. Difficulty concentrating, remembering, or making decisions is itself a listed symptom of perinatal depression, and it can show up without the sadness you would expect.
What if every test comes back clear? That is genuinely useful information, and it makes the attention-and-load explanation the likely one. Protect the moment information goes in, since divided attention at that point is what damages later recall — a working condition to solve, not a permanent loss to accept.
