hi,

my DS is 2 years old and for a while now we have noticed that when he hurts himself and cries he turns blue really quickly, it is after that initial scream after hurting himself and once he lets that long scream out and breathes in he pinks up again really quickly, what shocks me though is how quick he turns blue, it is literally seconds, is this something to worry about (im starting to worry there is a cardiac problem that he changes colour so quickly)

my DD who is 4 never changed colour like he does

thanks for any advice
