[Developmental delay in breastfed children due to inadequate diet of the mother].Ned Tijdschr Geneeskd. 2006 Mar 04; 150(9):465-9.NT
Two infant boys of 7 and 12 months respectively who presented with symptoms of failure to thrive and developmental delay were diagnosed with vitamin B12 deficiency. This deficiency is a rare condition in infants living in developed countries. It does occur, however, in infants who are breastfed by mothers with an inadequate diet. Both of the children studied were breastfed by vegetarian mothers. Following vitamin suppletion, both children showed signs of recovery. The importance of considering vitamin deficiencies in similar infants presenting with failure to thrive is emphasized. Moreover, maternal dietary habits in breastfed children should be checked. To prevent irreversible neurological damage, early recognition of any nutritional deficiencies is important.
