#AskTheExpert Hi, my daughter has completed 8 months a week back. She is rolling over back and forth.If she wants to reach any nearby objects she will keep on rolling back and forth and then gets it. Is this also a milestone ? My elder one used to crawl by this time. her weight is 6.7 kg. She is pretty much between 3rd to 15th percentile from birth. Should I be worried about the delay in milestones? Kindly suggest
