How many times can people say that and what is the best reply We have 1s who's 6 many of his peers have brothers and sister younger than them. My ds has started to struggle at school a little and we have asked a former teacher to tutor him a little now i feel like an outcast as another mother found out and the whole ' well they only have one ....' raises its head. The fact we have tried for another to no sucess!( not that they know this) and feel we need to help our son before he falls behind to far seems irrelevent .....it makes me so angry...
