Can a baby actually change a man?

So quick background, husband and I dated in high school, got married right after graduation (at 18), both joined the army, and here we are 4 years later, stationed overseas with our first baby who is now 5 months old. Before we had her, we loved each other, but communication was terrible and we fought often. We were BOTH very immature and didn’t know how to deal with being married honestly. However, I would say I figured it out sooner, not gonna lie. I know women mature faster than men though (usually). Anyways, before he would just play video games non stop, he never cleaned, never tried saving money, and would just fight with me constantly because he wanted to do what he wanted. We were on the verge of divorce. I ended up getting pregnant. And as soon as our daughter was born, it was like a flip switched. I didn’t even ask him to, because I was still considering divorce. He stopped playing video games often, he probably cleans more than I do, he even went to financial counseling (on his own, I didn’t even ask him to) so we could have a plan to save money. I asked him what happened, and he said that she changed his perspective on life, and he wanted to make sure he put his family above everything from here on out. And apologized for how he acted in our marriage. And he has been steady with that for the past 5 months (since she was born). I am so happy, just scared it’s only temporary. Has this happened to anyone else?
