DH and I have been struggling with our relationship for a while now, and things have gotten worse since DS was born. We both agreed not to argue in front of him, but there have been three or four occasions since he arrived where we’ve had raised voices. I feel absolutely terrible about this and so guilty and worried that it’ll affect DS, who is only four months old. He’s generally a smiley happy baby, but could hearing our arguments have impacted him?
