I think the biggest challenge with having two kids (or more, I'd imagine) is reminding myself not to compare them. Just because Makani was this way at four months doesn't mean Aurelia will be. She is her own person, and has her own path and is doing it just as she should be. My job is to remember that, and keep encouraging.
Every time my babies get older, as much as I miss that itty bitty phase (and that delicious newborn smell), I can't help but delight in their milestones and cheer them on as they become aware of their own personalities.
I've been happily basking in my newborn honeymoon. Well, we all have. I'm exhausted, sure, but oh my gosh, Ellie smiled for the first time this week and all was forgotten.
I am loving everything about having two babies. Life really feels complete right now.
