The title is something of a misnomer, since in many circumstances there aren't many ways to "deal" with morning sickness - one simply survives it and recovers afterward! But there are some tips and tricks to getting through that time period, and here are a couple:
(*Note: You'll notice that I said "morning sickness" and not "hyperemesis" - the two are entirely different beasts, and these tips aren't too applicable to hyperemesis, where the whole name of the game is simple survival. These tips are for a mama who is feeling badly - but well enough to be at least moderately functional - in other words, normal to moderate NVP rather than active HG.)
Nix the Kids' Pajamas
I actually learned this tip from a friend in culinary school many, many years ago. She had to get her three children up and out, and herself to school, by 5:30 a.m. in the morning. Definitely not an ideal situation, but one of the ways she made it work was by dressing all the kids (and doing the girls' hair) at night so that they could skip the "getting dressed" stage in the morning. Results aren't perfect, of course, but this technique works well to reduce laundry and mama's workload - especially if your husband helps with nighttime routines (like mine does!). This actually works so well that... we're still doing it, at least with our eldest. (I know, shameful! But it works so well!)
Bring on the Disposables
Real dishes are great... but in times of great stress and strain, the niceties of life go to the wall. Disposable plates, napkins, cups, silverware, etc., are indispensably helpful when one is too sick to deal with mountains of dishes.
Break the Laundry Rules
Here is what I did for laundry - I did one load a day, and that load contained everything. Darks, whites, lights, jeans, towels, kitchen laundry - whatever needed to be done that day was washed together and dried together. I daresay I broke some universal laundry laws and should be punished harshly, but it was a real life-saver. I still do it when I'm in a big rush!
Again, these rules only apply for a mama who is only moderately ill (as I was during my last two pregnancies, due to proper medication and God's mercy). Almost nothing applies when there is true hyperemesis and a mama is confined to bed (or hospital), as happened to us during our first pregnancy. But when NVP is mild to moderate, various lifestyle modifications like these can be very helpful.
What suggestions would you add to this list for a mama dealing with morning sickness?
