Baby blues vs. postpartum depression

The key differences are timing, intensity, and duration. Baby blues are mild, start within days, and fade by about two weeks. If symptoms last longer than two weeks, get worse, or interfere with caring for yourself or your baby, it may be postpartum depression—and that deserves evaluation.

What helps?

Rest wherever possible, accept help, eat warm and regularly, hydrate, and stay gently connected to others. The blues are a normal adjustment to the enormous hormonal and life shift of birth. Watch the two-week mark.

The nutrition connection

In the first fragile weeks, warm, easy-to-digest, nutrient-dense meals—soups, congees, iron-rich broths—stabilize energy and mood while the body recalibrates. This is the heart of the “sitting month.”

Common questions

Frequently asked

How long do the baby blues last?

They usually peak at days 4–5 and resolve within two weeks. Longer than that warrants an evaluation for postpartum depression.

Do baby blues need treatment?

No. They resolve on their own with rest, support, and nourishment. Persistent or worsening symptoms do need attention.
