Baby turning over

Fathima

My baby is 6 months (will be 7 on the 30th)

She is not turning over yet but she turns to her both sides. If I helped her she will fully turn over & will go from tummy to her back with no help sometimes, also she is not sitting yet unassisted. when I talk to her pediatrician, she said that she might have a developmental delay and need physical therapy. Need to know u guys' experience if anyone hv experienced this.(1st time mama here 😫🥺)
