nixon was crawling at 5.5 months and when he was 10 mths ppl said hes not walking coz hes too big !! but he walked at 13mths and is very mentally sharp .... in my eyes (with out the doubts) there is nothing wrong with nixon ... and i feel for anyone who has a fat or skinny baby ... it is a sad world when women (and men) are extremly image concious that we have to bring the purely innocent in to it ... and then play on mothers minds an evil game that we can never be good enough if they are too fat or too thin !
