Dont have to worry. She just needs more confidence in letting go. Try to encourage her by walking a few steps handsfree. Dont put pressure on her. My son’s infant care let him push weighted boxes to practice walking. Box must not be empty or too light else she’ll fall flat.
No need to worry:) it’s still within the normal developmental range. Just continue to encourage her to walk and stand. My first child walked independently at 16 months. She’s now running around every day 😅
