Baby walking but doesn’t go from sit to standing up on own

My girl started walking last week. However she doesn’t go from sitting to standing up on her own, she has to have something to pull up on. Then she takes off. But if she blops on the floor she scoots to something to pull up on. Any other walkers do this? Should i worry?
