sam has always seemed particularly bright, walking and talking early, conversations with him were like those with an educated adult. however, these last few months he doesn't seem to have moved forwards at all, and DS2 (13.5 months his junior) is overtaking him. for example, he is getting nowhere with reading and has been on flash cards for 2 years (usually 4 months!) despite trying hard. His eating is still at a stage where I feel I have to give him plastic crockery (the breakages got unaffordable) and truth be told, I would give DS2 much more complex jobs / activities if I were not sared about Sam's self esteem, as he is very concerned about being 'big brother'.
Is this the way it will be? Do I have to let DS2 pass him developmentally, or is Sam having a blip that will restart?
