time to roll over???

Kyla

​​​​​​​​​​​​​​​​​​​​​​​my little boy will be 4 months on the 27th and he just rolled over for the first time a couple days ago I was wondering if anyone else's baby started rolling at a such a young age a lot of people told me that's kind of odd that a almost 4 month old is rolling over already
