Dear. ..Baby ki jab neck tikne lag jati hai tab baby ko tummy time diya jata hai usme chin or chest up hote hai abhi apka baby 1 month ka ,to abhi ye milestone achieve nhi kiya hai jab bhi karta hai aap ispar tik kariye ..

It's a milestone Ipsita, it happens by 3 months. Baby will roll over to the stomach and lift their chin.. it's just a Growth tracker only by 3 months it will happen and then you can tick mark. Till walking milestone achieved the growth tracker will be shown.
