It's been really interesting having three kids that are essentially peers (Anna's 8 months older). When we first brought the boys home, there was a marked difference between them and Anna, but now it's kind of like having triplets. They love to hug each other, play together, serve food to one another, get into trouble together...it's almost like every day is a party!
I'll be honest and say that the prospect of having three kids so close in age sometimes worries me a little, just from the standpoint that I don't want a child feeling lost in the crowd, attention starved, etc. One of my biggest prayers for my children is for them to feel valued and special and loved individually, by us as their parents.
And God has been amazingly faithful! The kids love each other, would be lost without one another, and have honestly never shown signs that they are jealous of mom and dad's attention or love. So far I'm loving the fact that these kids will grow up as friends and peers. We're really careful about guarding their space (for example, if someone's wanting to play alone or something), and not being pushy about them interacting--that seems like a recipe for disaster.
Anyhow, I feel so blessed by the fact that my kids like each other, and look forward to the years ahead.
