Great suggestions so far!
I'm a nurse who works with pregnant women, so here's my spiel:
-Small, frequent amounts
-Avoid greasy, spicy foods
-Peppermint & ginger are natural tummy-settler-downers; try
peppermint tea, ginger tea, ginger snaps, peppermint or
ginger altoids
-Some women find sour things helpful: lemonade, lemon
candy, citrus fruit
-Some women find salty things helpful
-Some women find cooking, esp. meat, sets them off
-Sometimes certain odors make women feel sick
-Some women crave what their body can keep in...follow
cravings (no dirt, clay, cornstarch, etc
)
-Ask the doc/midwife about extra B6
-Try Sea-Bands (acupressure wrist devices found in drug
stores; developed by the Navy to help seasick sailors.
-If none of this works, ask your doc for prescription
stuff (unfortunately, most of them cause drowsiness)
NB: although the do-not-eat lists seem nitpicky, they're based on fact...no one's goal is to dictate to mom, but to ensure she has the healthiest possible pregnancy/baby.
Very important: if mom goes more than 48 hrs without being able to hold food in, or more than 24 hours without being able to hold down liquid, she needs medical attention
Hope this helps!
Congratulations, future grandma!!
