Down syndrome is one of the most common chromosomal abnormalities among newborns (Ergaz 2017, Glivetic 2015). Breastfeeding is highly recommended for babies with Down syndrome (n/a 2014) as it provides prevention from infections and celiac disease (Weijerman 2013), from malocclusion with crossbite and open bite (Oliveira 2011 and 2010) and from acute leukemia ( Flores 2009) and facilitates the development of speech and language (Weijerman 2013). Breastfeeding is possible for babies with Down syndrome. Babies with Down syndrome do not inevitably have initial feeding problems and can be breastfed successfully (Ergaz 2017, Raquel 2017, n/a 2014, Colón 2009, Aumonier 1983). But less frequent breastfeeding has been found among babies with Down syndrome than in the general neonate population (Glivetic 2015, Weijerman 2008, Pisacane 2003), especially if they are very young (n/a 2014), have poor suction and cardiac malformation ( Aumonier 1983) or are admitted and separated from their mothers (Colón 2009). Self-confidence and maternal perseverance (Raquel 2017, Aumonier 1983) together with active support for breastfeeding, education and collaboration between members of the health care team and the collaboration of breastfeeding specialists (LLL Faq 2016, T. Board 2008) are essential for the successful breastfeeding and should become a relevant health monitoring point for children with Down syndrome (Nal 2014, Pisacane 2003, Colón 2009). There are specific growth charts for girls and boys with Down syndrome.
