I know you love him, but he may do better in a calm adult home. Another forum member went through a similar painful period with her boy who was nipping her kids and her friend's kids. She found a woman who had experience with headstrong basenjis and though painful, she made the decision to let him live in a home better suited to the basenji. A dog that bites may eventually have a sad ending. I hope you can find a behaviorist and work with them, or think of finding Simba an adult home. I don't mean to sound harsh, but the reality is that a dog that bites kids is a liability.
Good luck to you, this will be a lot of work to redirect Simba's behavior.

I was going to tell my story when I realized this was about me and Otis.
We rehomed him after him nipping at the kids and us a few times. He is now in an adult only home and thriving. He has not had a single issue with growling (excepet when the new vet grabbed him rather roughly to check his teeth..he growled, the vet got the point and on they went..) or biting. He has mellowed out a lot, I think mainly from being in a home where he is not having to prove himself boss at all times..she (the new mommy) made it very clear from day 1 that she is the boss..and it works wonders on him. We tried doing that here, but with kids coming and going he constantly tried to be their bosses and the firm hand that was needed was not always there.
After taking him to a behaviorist he was diagnosed with Resource guarding, something that is highly fixable, with a stern upper hand and time.
We also had his thyroid checked by Dr Dodds, all was good on that front.
I know you are going through a hard time with difficult decisions ahead of you, but don't you rather do something now as supposed to when you are forced by law, because he hurt somebodies child bad enough?
That was why we went ahead and rehomed Otis..he deserved a new chance at a long life ahead. We miss him terribly, my 5 yr old asks constantly when Otis is coming home, but with time it will get better..Otis has lived with his new mommy for three weeks, so it is still very fresh in our mind and heart.
I wish you and your family best of luck, my thoughts are with you..
