I have a six month old baby and he's starting to explore his voice more. Some people (his aunts and uncles) play with him by letting him follow them, making a shreiking sound or more like a scream. I do not like this but this keeps going on. I am working far and my baby is with his dad. I told his dad that I do not like this but he does nothing about it and says they are just playing with him. Am I being too sensitive about this?
