My Baby is Walking at 10 months

So Roman has decided to follow in his sisters' footsteps and walk early...BOO HOO! He's been walking since the end of June early July he started standing and stepping. We just took him to the Stride Rites here for his first shoe only to find out he is beyond a first shoe! He was actually running around in the store. Okay, so I was in denial.  So Eden started walking at 9 months, Lola 10 months and Roman 10 1/2 months. What's the hurry? Don't know...
