I think it always comes harder when a new child has been introduced into the mix. Those first moments of going from 0 to 1 or 1 to 2 or, in this case, 2 to 3 bring with it a season of trying to find the groove. And, while it's all normal and natural, at the time, it really just feels like trying to find the way to LEAST neglect everyone you love.
How do you bond with the new one while not completely cutting out your oldest's naptime routine? How do you still take time to sing to your daughter before bed without letting on that you have one foot out the door to hold the baby?
Don't get me wrong, it has been overwhelmingly happy to add a child to our home, and to watch the older two kids learn to love their baby brother - who overnight went from picture and idea to in-the-flesh always-hungry human being. It has been overwhelmingly happy to sit back and watch them become siblings, and watch us become a family.
Having enough love for one more is never the issue. It's having enough time to love the way you want to. And having enough patience, enough grace, enough sleep....
