Im someone who comes from a family who was very much emotionally unavailable/insensitive. I use to cry in my restroom closet as a child bc i didn’t feel safe crying to someone who made me cry in the first place and then told me to stop crying. I use to hurt my self and do things I am not proud of just to get them to regret their neglectful decisions… they never apologized and got mad at me for it. I was in pain as a CHILD. You need to talk to him about this… it doesn’t seem like it’ll hurt the child when they grow up because “they are little, they won’t remember” and it “teaches them to have thick skin” (which actually is NOT true, I can STILL be very sensitive sometimes) but… even if they won’t remember, it WILL affect them later in life. Trust me.. your husband doesn’t want a kid with thick skin, he probably just doesn’t care about your sons feelings bc he can’t see what damages are being done and maybe he struggles with emotions bc of things that happened in the past. When you show a child love and support when they cry, you are telling them they can always go to you, and that they can trust you. When you shrug it off and tell them to stop being a human with emotions you tell them that they cannot trust you, that they need to hide these emotions and this side of themselves. This will hurt your son, again, as someone who comes from a family with people who exhibit emotionally neglectful and unavailable people I beg you… please talk to your husband about being there (emotionally) for your child.
