Cal's been walking for a few weeks now and all of a sudden in the last couple of days, he's been stumbling & falling a lot. It concerns me a bit, as he had been very solid on his feet for some time now. He's been wearing a different pair of Robeez from what he normally wears, and they are well-used (from his cousin). He's worn them before, but not since he's been walking. But they are exactly like the other pair he wears all the time - same size and everything. If it were a more fitted shoe I might think that the sole or arch had worn down, and that was causing a problem, but you know Robeez...they're just glorified socks.
Just wondering if this is normal?
