We had to buy DS a blanket while on holiday as he was getting cold in his wheelchair, the next day we were on our way out and Dd2 (who has only just turned 4) when she ran back into the caravan and grabbed the blanket, and said 'DS needs it as he has wobbly legs!!' We have never explained to her about DS's cerebral palsy as it is part of our every day life, so I was shocked that she realised this, I am not sure if she realises that DD1 also has cerebral palsy but I am glad she is there to look out for her brother and sister
