"Baby brain": forgetfulness in pregnancy

Walked into a room and forgotten why? Lost your keys, your train of thought, and the word you were just about to say — all before lunch? Welcome to “baby brain”, the foggy, forgetful feeling many people notice in pregnancy. It’s real, it’s common, and it’s nothing to be embarrassed about.

What it feels like. Baby brain (or “pregnancy brain”) usually shows up as forgetfulness, absent-mindedness, difficulty concentrating, or feeling a bit mentally foggy. You might misplace things, lose your thread mid-sentence, or struggle to focus on tasks that were once automatic. It can be mildly frustrating, but it’s a normal part of pregnancy for many.

Why it happens. It’s likely a combination of things: big hormonal shifts, broken sleep and sheer tiredness, the mental load of a huge life change, and a brain that’s understandably a bit preoccupied. Poor sleep alone will fog anyone’s thinking, and pregnancy delivers plenty of that.

It’s not a sign anything’s wrong. Baby brain doesn’t mean you’re losing your marbles or won’t cope — it’s a temporary, well-recognised experience, not a reflection of your ability. For most people it eases after the birth (though newborn sleep deprivation can extend the fog for a while — that part’s the tiredness, not the pregnancy).

Small things that help. You can’t switch off the hormones, but you can lighten the load: lean on lists, reminders and phone alarms, keep a shared calendar, put keys and essentials in the same spot every time, and don’t try to hold everything in your head. Tackle important things when you’re freshest, and go easy on multitasking.

Look after the basics. The usual suspects make fog better or worse. Prioritise sleep where you can (naps count), stay hydrated, eat regularly to keep your energy steady, get some gentle movement and fresh air, and try to lower avoidable stress. None of it is a magic fix, but together they genuinely help your brain feel less woolly.

Be kind to yourself. Beating yourself up for forgetting things just adds stress, which makes focus worse. Laugh it off where you can, ask for help, and let some balls drop — this is a season of enormous change, and a bit of mental fog is a very reasonable response to it.

When to mention it. Baby brain is harmless, but if forgetfulness or difficulty concentrating feels severe, or comes with persistent low mood, anxiety, or loss of interest in things, talk to your GP or midwife — sometimes what feels like “just fog” is tied to antenatal anxiety or depression, which are common and treatable.

So if you’re feeling scattered, you’re in very good company — baby brain is a normal, temporary part of the ride. Prop yourself up with lists and reminders, protect your sleep, and be gentle with yourself. Your sharpness returns; for now, write it down and let yourself off the hook.
