That is my family!

Take your little one up, sit with him/her to the table and view together a family photo album.
Show the baby your family members - grandpas and grannies, aunts and uncles, sisters and brothers, cousins, etc., name them.
Demonstrate your positive emotions, let the baby touch the photos gently.
You can even read your little one a short poem about family!
Upload to the App your family photos, add some words about your baby's reaction to the process.
