This guide is general education that summarizes published research and guidance from groups like the American Academy of Pediatrics, the CDC, and the WHO. It isn’t medical advice, and every child develops on their own timeline. Your pediatrician knows your child; if something feels wrong, call them. In an emergency, call 911.

Twenty-six weeks and three days. Keys in the fridge, a word that won't come, a question you meant to ask at the appointment and remembered in the car park. Today is about that, and about not carrying it all in your head.

## Your baby

Around now your baby is around 35.6cm from head to heel, about the size of a cucumber ([NHS](https://www.nhs.uk/best-start-in-life/pregnancy/week-by-week-guide-to-pregnancy/2nd-trimester/week-26/)). There's a lot of movement inside the bump this week ([NHS](https://www.nhs.uk/best-start-in-life/pregnancy/week-by-week-guide-to-pregnancy/2nd-trimester/week-26/)). You'll be getting to know when your baby tends to be busy and when they're quiet, and that pattern is worth knowing well.

## Your body

The NHS lists possible forgetfulness among this week's changes, and it's careful about the label: "baby brain" is not a medical condition and is not scientifically proven ([NHS](https://www.nhs.uk/best-start-in-life/pregnancy/week-by-week-guide-to-pregnancy/2nd-trimester/week-26/)). What is on the list is tiredness, along with clumsiness and reduced coordination ([NHS](https://www.nhs.uk/best-start-in-life/pregnancy/week-by-week-guide-to-pregnancy/2nd-trimester/week-26/)).

Nights don't help. The kidneys are filtering extra blood and the baby presses on the bladder, so there are more bathroom trips at night, and slower digestion can bring heartburn that's worse after dark ([MedlinePlus](https://medlineplus.gov/ency/patientinstructions/000559.htm)). Broken sleep on top of a full diary is a lot to carry.

### The lists habit

- **Time:** 10 minutes to set up

1. Pick one place for every list from now to the birth: a sheet on the fridge, a shared note on your phone, or a small notebook in your bag. One, not three.
2. Start it with three headings: "Ask the midwife or doctor", "To buy", "To sort".
3. Empty your head into it now, everything that's been nagging, however small.
4. Every time a question surfaces, it goes on the list before you do anything else.
5. Take the list to every appointment, and read the first heading out before they ask if you have any questions.

**Make it work:** If you share the household, share the list. Two people adding to one page beats two people each trying to remember.

## Watch for

- **Normal:** busy times and quiet times for your baby, roughly the same each day. **Call your midwife or maternity unit straight away** if the movements slow down or stop; the NHS is clear on this ([NHS](https://www.nhs.uk/best-start-in-life/pregnancy/week-by-week-guide-to-pregnancy/2nd-trimester/week-26/)), and the CDC says there's no set number that counts as normal; a change from your baby's usual is what matters ([CDC](https://www.cdc.gov/hearher/maternal-warning-signs/index.html)).
- **Normal:** a foggy head after a broken night. **Seek care immediately** for dizziness or fainting, which the CDC lists as an urgent warning sign ([CDC](https://www.cdc.gov/hearher/maternal-warning-signs/index.html)).
- **Normal:** lying awake some nights. **Call your provider** before taking any sleep aid, including over-the-counter medicines and herbal products ([MedlinePlus](https://medlineplus.gov/ency/patientinstructions/000559.htm)).

## For you

Tired people forget things. That's the whole explanation you need, and it isn't a judgement on your mind. Whatever you call it, the fix is the same: write it down, and let paper do the remembering.

A warm caffeine-free drink such as milk, or a 15-minute warm bath, can help you settle at night, and short daytime naps can make up some of the lost sleep ([MedlinePlus](https://medlineplus.gov/ency/patientinstructions/000559.htm)).

If you're the partner: don't tease about baby brain, even kindly. Check the list instead, take three items off it this week, and cross them out where she can see.
