Walking?

Lana

My daughter turned 1 on the 13th, but shes not walking yet, and hasnt taken any steps on her own. She cruses on furniture, and can stand on her own for a few seconds, bit still crawls everywhere. I feel like every 1 year old is already up and walking! Is this normal or should I be worried yet? I heard it can take up to 15 months, but that sounds so late to me.
