Early weaning and separation from your mother can cause hyperactivity and anxiety later in life, a study has suggested.
Baby mice separated from their mothers and forced to undergo early weaning were found to be hyperactive and anxious in the course of the research.
The mice underwent maternal separation for four hours a day between two and five days after birth, and eight hours a day on days six to 16. They were also weaned early on day 17 as part of the experiment.
Those mice exposed to this treatment were found to be "hyperactive and anxious" when compared with control animals.
The study comes just days after separate research suggested breastfeeding a baby exclusively for six months helps prevent common infections.
