Let's see it!

Your baby is grown up enough to use actively his/her vision for the world exploring!
Offer the little one to have a look at the moving objects at your home. You can even place your baby's cot next to the window, so that the little one could see the sky and the clouds, tree branches, birds flying, etc.
Then go for a walk and show your baby a sparrow jumping, a dog running along the street, a cat sitting on a bench, etc. Pay the baby's attention to cars, to adults and kids. Tell the little one about everything you see. Thus he/she will learn a lot about the world around, improve the passive vocabulary.
Make photos of your baby looking at an interesting object, upload to the App. Write briefly what things and objects attract your baby's attention most at all.
