The birth of a new child in a family is always a source of joy and happiness. But for some women, baby’s arrival at home creates in them a blues, named “baby blues”. Baby blues is usually temporary and only lasts a few days. If after several weeks no change is observed, we speak then about postnatal depression.

In France, the number of women affected by the postnatal depression is estimated at 15%.

The most common symptoms include sleep disturbances, excessive tiredness , difficulty concentrating, irritability and disorders in mother-baby interaction.

To help moms, a team of New Zealand researchers was interested in the subject !

423 pregnant women participated in a randomized, double-blind, placebo-controlled clinical trial.

The supplemented group received daily 6.109 CFU of Lactobacillus rhamnosus from 14 weeks gestation to the 6 months of the baby. A placebo was given to the second group. At the end of the study, moms completed a questionnaire to assess depression and anxiety.

The results speak for themselves : during the postpartum period, women in the probiotic group saw their depression and anxiety greatly reduced compared to those in the placebo group.

A hopeful study for new moms! However, more research are needed to confirm these results.
