It's great that you and your wife are working together and supporting each other. Think of it as your trial for great things to come, and the continuous rewards of love and happiness are all worth it.

We had our first 2 children very close together, just 1 year and 3 months apart. Then we had our little one 6 years after our second child. Each child is uniquely difficult in their own way and caused their fair share of lack of sleep when they were babies. Now the two older kids are 13 and 12, and even our little one is 6. Not having enough sleep for days and weeks definitely sucks, but it comes and goes without you even realizing. It might seem like an eternity while living in it, but when I look back to those days, I definitely miss the feeling of holding that little delicate baby in my arm while feeding them and having them lean on my body while I brush/tap their backs to try to burp them. Hang in there man, before you know it, they've grown taller than your wife and are on their way to be taller than you.
