4 month old showing no signs of rolling

to the mommies house of babies who have started rolling, how far along before rolling they started to turn on to their sides? did they attempt to turn on their side daily after that?

my lo is 4 months today n when something like a toy or towel is kept on her chest she grabs it n turn on her side since a month, otherwise she just lays on her back without attempting..

i’m a FTM n already started worrying as she isn’t showing any interest in rolling..to top it she is 24*7 crying n hates tummy time( i’ve done everything humanly possible to put her on tummy n she just tolerate for a minute n screams afterwards)
