Do you mean walking slightly pigeon toed? If so, Bethany used to be terrible, so much so she was referred to a physiotherapist, who examined her hips, legs, feet and said they all looked normal and it is just a habit she is in and should grow out of it. The physio said it can be a few years before they grow out of it and after the first appointment she discharged Bethany with everything looking normal. Bethany doesn't so it as much now and only really when she is tired.
I would speak to your HV and see what they say xx
