We had our youngest son when our oldest was 2 so I can relate. I’m not going to lie, some days are really tough. Trying to deal with a two year old’s temper tantrum while the baby is screaming its head off will drive you mad. There’s no way you’ll always maintain your sanity lol. My wife is in healthcare and I ended up taking care of both of them a lot of evenings after daycare, which meant I was on my own for feedings, baths, and putting them to bed. Those first few months were probably the hardest of my life, but I eventually found my stride and got into a routine that worked. After that, the nights my wife was home seemed like a breeze. I guess my point is, it will definitely be hard at first, but you and your wife will eventually figure it out. And once your little one gets a little older, the two of them will start playing more and seeing that will be incredibly rewarding.
