If Your Twins Were Born This Week

Your twins are very early preterm and the odds of survival are better than weeks past. However, twins born during the 26th week still risk major medical complications and life-long health issues.

What to Prepare This Week

When Mom is 26 weeks pregnant with twins, get your twin diaper bag ready. You don’t need two diaper bags, just find a quality bag that can easily carry double the supplies without breaking your back.

  1. Week 26 was one of the tougher weeks emotionally for me. Those pregnancy hormones are still going wild! Over the last couple of weeks I feel like my tummy size has doubled! I’m spending a fortune on belly butter to soothe the itching. Im also experiencing burning hands and feet at bedtime which is really uncomfortable.

  2. I’m currently 26 weeks pregnant with twins and experiencing some of the symptoms mentioned in the post. It’s reassuring to know that I’m not alone in this journey and that there are other moms out there who understand what I’m going through. Thank you for sharing your insights and experiences!
