The study population consists of 32 babies with Down syndrome between 4 and 8 months old.

In this study, the investigators will compare the maturational development of the experimental group Down syndrome babies (will receive infant massage in the period between the two measurements) with the maturational development of the control group Down syndrome babies (will receive infant massage after two measurements). Assess both the development partial motor, cognitive, language and social, and also the maturational development global. Finally, measure also the ratio of development, both in the pretest as on the posttest. The test that will use to measure the development of them babies is the scale of development psychomotor of her first childhood Brunet-Lezine-R.
