14 month boy still toddles unbalanced after 5 weeks of walking, holds arms near shoulder level; very tall off charts. is that normal?

Evaluate Milestones: Your 14 mos old "walks unbalanced"; is "very tall off charts". Making an assessment of his development based on his walking alone is inadequate. A complete evaluation of his milestones is crucial in diagnosing developmental delay vs. a late bloomer. His growth history can elucidate many medical conditions. See your pediatrician soon, early intervention is key if your son is showing some delays.
