feline predicament ???? advise needed

[pugsmum]

We have had our cat for around 6 months , and got him when he was around 2 months old ..
Ds is 2 yrs and very boisterous with the cat he loves it to bits but obviously being 2 isnt very carful with it not spiteful but quite rough !
Today the cat bit/scratched him on the lip not sure exactly which as they were in the kitchen while I was the living room .
It was bleeding quite badly but only a small cut have had it checked out ?
But what I would like advise on is weather it is necessary to get rid of the cat ,
My immediate reaction was to get rid of him but then at the nurse said not to be silly because these things happen .
I am now unsure of what is best obviously I do not want to get rid of our cat he is lovley but ds does antagonise him , but do not want to risk ds getting hurt again ..
Am I over reacting by thinking of finding him a new child free home or is that the best thing to do

Advise please what would you do ??????

Remember that animals are a bundle of instincts and though the majority tend to be more considerate around children they are still running on fight or flight. A sharp, sudden pain (such as a tug on the tail) would make anything - even a human - have an involuntary reaction.
the cat clearly has patience with the child as this is the first time this has happened.
Not sure whether we should immediately jump to the bad-owner assumption on this but I agree, please don't leave toddler and animal unsupervised
