Peekaboo with a transparent handkerchief

Offer your little one to play peekaboo with a transparent handkerchief. At the age of 4 months it's difficult for your little one to understand that objects don't disappear when you cover them with something, so the task will help you to show that they are just hidden.
Cover your face with the transparent handkerchief and then throw it off. Comment your actions - "I'm hidden!"
Then cover your baby with the handkerchief, stimulate him/her to throw it off. Smile and cheer your little one on.
You can also hide and show toys and other things.
Make photos of your baby during the process, upload to the App. Write about your little one's impressions.
