Worried 😌

Hi mommies! Just a quick question, my 17-month-old hasn't steadily walk yet. He does walk for 5-6 steps and then will continue crawling. He climbs stairs confidently, he holds on cabinets to go from 1 point to 1 point. No issue on that. Should I be worried? PS: He started sitting and crawling quite late; around 10 months+. Did that affect his walking milestone? Thank you! 🌸
