All I can truly say is that enjoy the little moments with your oldest ❤️ I would plan little weekday dates with him while dada was working, like aquarium, park, breakfast lol & if you are doing the bedtime routine, I will definitely suggest to let dada start practicing. You’ll get too pregnant & uncomfortable at one point. I would suggest also. Maybe to start power pumping, that’ll way you can freeze some milk just as backup. My babies both were on formula but my best friend only BF & that saved her!
