This short book has beautiful illustrations showing mother animals giving their babies kisses to show their love. It's perfect for babies, but at 3 years old my daughter still likes it (and the Mommy kisses that she gets while I read it)!
Daddy's Girl by Garrison Keillor
Hands down, this has been our favourite daddy/daughter book. It's a sweet collection of poems showing the love and fun that men share with their daughters (a couple of them are pretty darn funny! The diaper changing poem is the best - C can even recite it!). This book makes a great baby shower or Father's Day gift.
Just in Case You Ever Wonder by Max Lucado
This book always makes me tear up! It's a beautiful book telling a child how God made them unique, and about how much their parents love and care for them.
