Almost identical to us. I’ve got a two month old girl and a 19 month old boy. It was really easy while I was on paternity leave (six weeks). I took care of boy 95% of the time and my wife took care of newborn girl. We didn’t have new parent jitters which made a world of difference. As you can see from my post above, things have gotten a lot worse. The boy is losing his mind multiple times a day because he wants my wife to hold him when she is holding/feeding newborn daughter. He can’t speak, so he just screams and runs in circles and breaks all the rules he knows. Also starting to get newborn “it’s time to fucking sleep” fatigue. It’s whatever for first month or two, but we are getting tired of it. 12 hours of my son going crazy in the day followed by 12 hours of daughter being a mediocre night time sleeper makes it a 24 hour a day process. I’ll continue to let you know how it’s going. I do think it will be good - my son already cares for baby daughter and wants to include her in things.
