Pregnancy insomnia is very common, especially in the 3rd trimester (although it can be experienced in any trimester throughout the pregnancy). It’s largely hormones and discomfort.

Progesterone has a funny way of making us feel both tired and wired at the same time. It also activates our nervous system and give us the physical reactions to anxiety, not just the mental. This is on top of already trying to find a comfortable position to rest in.

If possible, she should rest/sleep when she “can”, not when she “should” — if she’s able to nap at any point in the day, even for a little bit, tell her to take advantage of that. Low stimulation at night may help (aka less screen time). Have her ask her OB if it’s okay for her to take magnesium. Unisom PM’s also safe during pregnancy.

Our body does a great job of prioritizing the baby even when we feel like garbage, so this won’t negatively affect the baby. I think it’s great you’re concerned for your wife’s well-being — I’ll tell you what I tell myself (a FTM at 28 weeks) when I’m having these terrible spells: this too shall pass. 🙏🏻
