Talk to Pediatrician on Child Development

Hi my baby was able to sot unsupported pretty well by the time she was eight months old was able to roll in all sides by nine months, she is a year old now but beeds slight assistance like holding her legs slightly so that she can pull up to sit. Dhe still cabnot pull up to stand or crawl at all neither is she bum shuffling. She seems to be a happy n healthy baby has a weight of 10kgs plus. I have a son who is eight years old he has arrested communicating hydrocephalus ndhd all fo his milestones delayed.im just concerned since i have been through a lot fo problem before.. My daughter doesnt seem to show any of the signs or issues my son has but her milestones are concerning me. Doctors say she is in range and not delayed and uptil now all seems ok, plesse help me out in this regard wether she needs physical therapy or anything esle to make her learn standing and walking.
