What can I eat for my baby's development when I have morning sickness?
Eat whatever plain, starchy food you can keep down, and tuck in a few cold brain foods when you can: a chilled hard-boiled egg (choline and iodine), plain Greek yogurt, cold milk or cold roast chicken. Keep taking your prenatal. Ordinary morning sickness doesn't raise the risk to your baby (NHS). Ask your doctor about vitamin B6 if nausea is bad.

First, take the pressure off
Nausea and vomiting are very common in early pregnancy. They can hit at any hour, or last all day. For most women it eases by weeks 16 to 20, and the NHS notes that ordinary morning sickness doesn't raise the risk to your baby.
On a bad day, your only job is to keep fluids down and nibble your way through. When you can, add one brain food. When you can't, toast is fine.
What helps the nausea
The NHS suggests:
- Small, frequent portions of plain, starchy, low-fat foods: bread, rice, crackers, pasta.
- Dry toast or a plain cracker by the bed, eaten before you get up.
- Cold foods if the smell of hot food sets you off. Cold food smells less.
- Small sips of water or other drinks, often.
- Ginger foods or drinks. Check with a pharmacist before taking ginger supplements.
- Rest, because tiredness makes nausea worse.
- Acupressure on the wrist, with your fingers or a wristband.

Brain foods that go down easy
The trick is to tuck a few brain nutrients into the bland, cold foods you can stand. Nutrient amounts here are from the NIH Office of Dietary Supplements.
| Food (cold or plain) | What it brings | Why it works when you feel sick |
|---|---|---|
| Hard-boiled egg, chilled | Choline (147 mg), iodine (31 mcg) | No cooking smell. Make 6 at once. |
| Plain Greek yogurt, 3/4 cup | Iodine (87 mcg) | Cold, smooth, a little tangy |
| Cold milk, 1 cup | Iodine (84 mcg), choline (43 mg) | Easy to sip slowly |
| Cold roast chicken | Choline (72 mg per 3 oz), iron | Already cooked, no smell |
| Toast from bread made with iodized salt or iodate | Iodine | Plain carbs plus a hidden bonus |
Why these nutrients? In the first trimester your baby can't make its own thyroid hormone yet and depends on yours, and your thyroid needs iodine to make it. Choline helps build new brain cells, and most women fall short of the 450 mg target. Two chilled eggs alone give about 294 mg. See eggs in pregnancy and iodine in pregnancy for more.
Other ideas that fit the "cold and plain" rule: cheese and crackers (pasteurized hard cheese is fine), a cold glass of milk with dry cereal, or plain rice with a little chopped cold chicken. Use iodized salt for any salt you add.
A sample sick day that still counts
Here's what a rough day can look like using only cold, plain foods. Eat what you can and skip what you can't.
| When | Food | Brain nutrients |
|---|---|---|
| Before getting up | A few plain crackers | Something in your stomach |
| Mid-morning | 1 chilled hard-boiled egg, dry toast | Choline 147 mg, iodine 31 mcg |
| Lunch | Plain pasta or rice with 3 oz cold roast chicken | Choline 72 mg, some iron |
| Afternoon | 3/4 cup plain Greek yogurt | Iodine 87 mcg |
| Evening | 1 cup cold milk, sipped slowly | Choline 43 mg, iodine 84 mcg |
That adds up to about 262 mg of choline and about 202 mcg of iodine from food, before your prenatal or any iodized salt. Not perfect, and that's fine. On a better day, add a second egg.
Your prenatal and folic acid
The neural tube, which becomes the brain and spinal cord, finishes forming by about day 28 of pregnancy. If you're taking 400 mcg of folic acid a day, keep going. That one pill matters most in these early weeks.
If your prenatal makes you gag or seems to make the nausea worse, don't just quit. Ask your doctor or midwife whether a different prenatal would sit better. Our prenatal checklist shows what the label needs to cover.
Vitamin B6 and other help
The American College of Obstetricians and Gynecologists (ACOG) lists vitamin B6 as a first step for pregnancy nausea, adding doxylamine (an antihistamine) if needed. The B6 and doxylamine combination has been linked to about a 70% drop in nausea and vomiting.
The B6 amounts used for nausea can come close to the safe upper limit of 100 mg a day, so get the dose from your doctor, not a store shelf. Your doctor can also prescribe other anti-nausea medicines that are safe in pregnancy. A good question to bring: "My nausea is making it hard to eat. Should I try vitamin B6, B6 with doxylamine, or something else? And is my prenatal vitamin making it worse?"
What not to worry about, and what to watch
Not eating "enough." You don't need to eat for two. MedlinePlus estimates that a woman at a healthy weight needs about 1,800 calories a day in the first trimester, close to what most women ate before pregnancy. Quality matters more than quantity right now, so add a brain food on the days you can.
Caffeine as a pick-me-up. If coffee is the only thing that feels normal, keep it under 200 mg a day. One large brewed coffee can be all of it. See the caffeine limit.
Food safety still counts. Cold foods are great, but heat deli meats until steaming, choose pasteurized milk and soft cheese, and cook eggs until firm.
Severe sickness is different. Hyperemesis gravidarum, a severe form of pregnancy sickness, can cause dehydration and needs treatment. The warning signs are below. Don't tough it out.
Do this
- Boil six eggs on a good day and keep them in the fridge as cold, no-smell snacks.
- Keep dry crackers by your bed and eat a few before getting up.
- Sip fluids often in small amounts, and rest when you're wiped out.
- Keep taking your prenatal with folic acid, and ask about switching if it makes you gag.
- Ask your doctor about vitamin B6 or B6 with doxylamine if nausea is making it hard to eat.
When to ask your doctor
Check with your doctor or midwife first if…
- You're thinking about ginger supplements (check with a pharmacist first).
- You want to try vitamin B6, since nausea doses come close to the upper limit.
- You take any other medicine or have a medical condition.
Call your doctor now if…
- You can't keep food or fluids down for 24 hours.
- Your pee is very dark, or you haven't peed in 8 hours.
- You feel faint when you stand, or you're losing weight.
- You have belly pain or a fever with vomiting, or blood in your vomit.
- You have any vaginal bleeding, fluid leaking or severe pain (call your doctor or 911 now).

Can morning sickness harm my baby?
Ordinary morning sickness doesn't raise the risk to your baby, the NHS notes, and for most women it eases by weeks 16 to 20. Severe sickness that stops you keeping fluids down is different and needs treatment, so call your doctor or midwife if that happens.
What should I eat first thing in the morning?
Keep dry toast or a plain cracker by your bed and eat it before you get up. Once you're up, try small portions of plain, starchy food. Later in the day, add a cold brain food like a chilled egg or yogurt if you can.
Is it okay to skip my prenatal when I feel sick?
Try not to, because folic acid matters most in the early weeks. Ask your doctor or midwife about a prenatal that's easier to get down. If you can't keep anything down for 24 hours, call your doctor.
Does vitamin B6 help morning sickness?
ACOG lists vitamin B6 as a first step, adding doxylamine if needed, and the combination has been linked to about a 70% drop in nausea and vomiting. Because nausea doses come close to the safe upper limit, get the dose from your doctor.
