Real macarons are so delicate and hard to transport, plus, if you don't eat them they don't exactly stay well-preserved. It's good to have a set of fake, durable display cookies too.
Can't you see this cake inspiring an entire room's worth of decor? I like kids decor that can transition through the years. I feel like pink and blue are such baby colors that don't apply quite so well when they become toddlers. Green and yellow are always classic.
