Have you thanked them for the part they play in yours?
I made these fun bookmarks for my Thanksgiving packets with leftover scrapbook paper from another project! I added each child's photo and printed Philippians 1:3,7 in each child's language. It says "I thank my God every time I remember you......because I have you in my heart!" To top it off, I included a copy of one of my favorite songs, "10,000 Reasons" and encouraged each child to take time to be thankful for God's goodness!
Thanksgiving is past, but you can say thanks all year round! Tell your child that he or she is valued. Take time to say "thank you" for the letters, drawings, and love that your child lavishes on you!
