Hopefully you find a behaviorist and soon! My dogs cannot tolerate the high pitch noise of little ones. I believe it either hurts their ears or reminds them of an animal in distress. Either way, they cannot take the sounds and puts them into prey drive. Very likely your dog is going into prey drive and is confused as baby is a cherise to you. I don't know the bestway to desenitize a dog to this. I lock my dogs in the crates when Grandbaby visits. Way toeasy a markfor them!In a perfect world you could make the baby'shut up', but that won't happen. So in some way you need to make your dog ignore. Good luck!
