Wow. My third baby is almost 4 months old, and I've begun singing these hymns to him. I wish I would have had this book with my older 2 kiddos. Reading/singing to babies is the one of the simplest and greatest ROIs you'll have, and what a great way this is to spend that time. Many times board books can become passive for parents, especially as we read them again and again, but thus little series keeps our hearts and minds aligned with truth while we care for our young ones.
