Offer your baby to play the game, beneficial for spatial coordination development.To arrange it you'll need a teddy toy. When your baby lays in the cot, get their attention on the teddy toy. The bear or the doll can wave to your baby, greet him/her, dance, jump, sing a funny song, etc.
Let the toy say: "Bye-bye!" and hide it. Then the toy should appear on the other side of the cot and greet the baby again.
Smile at your baby, show that you are glad to see the toy. Repeat your actions 2-3 times, then let your baby explore the toy.
Make photos of the process, upload to the App. Write how your little one reacted to the toy's actions.
