What to Prepare This Week
When Mom is 17 weeks pregnant with twins, you need to remind yourself that you need to help Mom stay healthy during this pregnancy. Be her helper, assistant, and reminder of what the doctor has told her she needs to be doing. Get in this habit now so that when possible bed rest comes later, you’ve established a good routine of care.
By the time Mom reaches 17 weeks pregnant with twins, she might be feeling the babies moving around. Unfortunately, you still can’t on the outside. It is exciting to hear her describe the fluttering feeling but also disappointing when you so desperately want to feel them yourself.
