When I think of pregnancy, the only real serious drawback for me was that stinking nausea.
So, naturally I cleverly developed some coping skills to deal with nausea:
Get out of bed only when you absolutely have to. Great argument for the toddler still sleeping with you, they like to stay in bed and talk to you for a long time in the morning. Could set up Lego in the corner of your room to ensure a lengthier stay in bed.
Get up only long enough to stockpile your snacks for the day.
Lay on the couch all day. This is the cornerstone of dealing with morning sickness effectively. And not having any expectations for yourself.
Do not make meals. Feed the children from the snack basket you prepared in the morning.
Eat all day. It is only when you are actually sleeping or chewing that you get any relief from morning sickness.
Only play games with the children that require you to be the patient.
If someone offers you their help, say, Yes Please.
Go to bed as early as possible.
Know that this, too, shall pass. Know, too, that you can catch up with all that backed up housework when the nesting starts. God knew what He was doing.
