This is called "in-toeing" and is very common. I noticed it on my now 5 year old daughter when she was 18 months old. She has been seeing an orthopedist from Children's Hospital every 6 to 12 months since then. Basically, they don't do anything by way of braces or corrective shoes anymore. The doctor told me that they don't really help and are just a nuisance for the child. Once they determine that her hips and bones are normal, you just wait for her to grow out of it. My daughter's gait has improved steadily over the years and the intoeing is now only noticable if you are looking for it and if she is tired or wearing clunky boots. Good luck and try not to worry!
